-# InternalProps
-
-The `@bento/internal-props` package provides internal utilities and components used across the Bento project to bypass restrictions, filtering of props, or triggering of data-override props within the Bento ecosystem. This package is strictly for internal use by @bento-based components or those who use Bento to create design system components.
-
-> ⚠️ **Warning**: This package is not intended for public consumption and is subject to change without notice. It should only be used by internal Bento components or design system implementations.
-
-## Installation
-
-To install the package, use your preferred package manager:
-
-```shell
-npm install @bento/internal-props
-```
-
-## API
-
-The package exports two main functions:
-
-### useInternalProps
-
-Extracts internal properties from a set of properties by removing the specified prefix.
-
-```tsx
-import { useInternalProps } from '@bento/internal-props';
-
-const [props, internal] = useInternalProps({
-  '$$bento-internal-1-foo': 'bar',
-  '$$bento-internal-1-baz': 'qux',
-  regular: 'prop'
-});
-
-console.log(props);   // { regular: 'prop' }
-console.log(internal); // { foo: 'bar', baz: 'qux' }
-```
-
-The function accepts two arguments:
-- `props`: The properties to extract from
-- `prefix`: (Optional) The prefix to remove from the properties. Defaults to `$$bento-internal-{major}-`
-
-### toInternalProps
-
-Converts a set of properties to internal properties by prefixing them with the specified namespace.
-
-```tsx
-import { toInternalProps } from '@bento/internal-props';
-
-const internal = toInternalProps({
-  foo: 'bar',
-  baz: 'qux'
-});
-
-console.log(internal); // { '$$bento-internal-1-foo': 'bar', '$$bento-internal-1-baz': 'qux' }
-```
-
-The function accepts two arguments:
-- `props`: The properties to convert
-- `prefix`: (Optional) The prefix to use for the internal properties. Defaults to `$$bento-internal-{major}-`
-

-<Source language='tsx' code={ SourceDemo } />
-<Story of={Stories.Demo} inline />

+
+## Lock Boundaries
+
+When you're building a design system on top of Bento, you'll often compose components together internally using slots, className, and style props. Without lock boundaries, all these internal modifications get flagged with `data-override` attributes, which makes it really hard to tell the difference between your design system's internal structure and actual customizations made by people using your design system.
+
+Lock boundaries solve this by creating a clear line between "this is how we built it" and "this is what someone changed." Think of it as drawing a circle around your component and saying "everything inside this circle is intentional design system composition."
+
+### How it works
+
+The mechanism uses a generation counter. When you wrap a component with `<Environment lock={true}>`, Bento increments a generation number. Every slot modification gets tagged with the current generation number. Later, when the component renders, Bento checks: was this slot created before or after the lock? If it was created before (lower generation number), it came from a consumer, so it gets flagged. If it was created after (same or higher generation), it's part of your design system's internal structure, so no flag.
+
+Here's a practical example. Let's say you're building a design system and you create a component that internally uses a Button and RadioGroup:
+
+<Source language='tsx' code={LockNoOverrideExample} />
+
+Notice the `<Environment lock={true}>` wrapper. Everything you do with slots inside that wrapper is considered internal composition. The `root.trigger` slot that changes the button text, the `group.label` and `group.description` slots that style the radio group—none of these get `data-override` attributes because they're all happening after the lock.
+
+Now when someone uses your design system component and wants to customize it:
+
+<Source language='tsx' code={LockWithOverrideExample} />
+
+This slot modification happens *before* entering your locked environment (because it's passed as a prop to `DesignSystemVersion`). Bento sees it crossed the lock boundary and adds `data-override="slot"`. Now you know exactly what your consumers are customizing.
+
+### When to use this
+
+Use lock boundaries when you're building a design system that other developers will consume. If you're just building application components or working directly with Bento primitives, you probably don't need this. The lock is specifically for the boundary between design system authors and design system consumers.
+
+You might skip locks if you're debugging and want to see all modifications flagged, or if you're building one-off components that won't be reused across teams.
+
+### What you can do with this information
+
+Once you have accurate `data-override` tracking, you can build tooling around it. You could create a development mode that warns when consumers override certain slots, track which components are being customized most often to inform your roadmap, or generate migration guides when you need to make breaking changes by analyzing which overrides exist in production.
+
+The `data-override` attributes are just data attributes in the DOM. Your dev tools, browser extensions, or analytics can read them to understand how your design system is being used in the wild.

+## Lock Boundaries
+
+If you're building a design system on top of Bento and distributing components to other teams, the `lock` prop helps you distinguish between your internal component composition and modifications made by your consumers.
+
+The problem this solves is simple: when you compose components internally using slots, all those modifications show up with `data-override` attributes. This makes it impossible to tell which modifications are part of your design system's intentional structure versus which ones are customizations made by the people using your components.
+
+Here's what it looks like in practice:
+
+<Source language='tsx' code={LockNoOverrideExample} />
+
+The `<Environment lock={true}>` wrapper tells Bento that everything inside is internal to your design system. When you modify slots within that boundary (like changing the button text or adding className to the radio labels), those modifications won't get flagged with `data-override`.
+
+But when someone using your design system passes their own slots:
+
+```tsx
+<DesignSystemComponent 
+  slots={{ 'composed.root.trigger': { children: 'Custom Text' } }}
+/>
+```
+
+That modification happens outside your lock boundary, so it gets flagged with `data-override="slot"`. Now you can tell the difference.
+
+This information becomes useful when you want to understand how your design system is actually being used. You could build dev tools that warn about certain overrides, track usage patterns to inform your roadmap, or generate migration guides based on which slots people are actually customizing in production.
+
+For more details about how the generation tracking system works and when to use locks, see the [Concepts](/docs/environment-concepts--docs) page.

Subject: [PATCH 15/19] refactor: convert browser tests to use vitest snapshots

- Convert use-props, slots, and environment browser tests to use toMatchSnapshot()
- Add withLock HOC for wrapping components with locked Environment
- Fix use-props node tests to use locked environment when testing data-override
- Add @bento/environment and @bento/use-props as devDependencies for slots tests

-# Composition Guidelines PDR
-
-## Purpose
-
-Establishes guidelines for component composition using Bento primitives and slots. Defines how to build composite components that introduce logic while remaining composable and customizable.
-
-## Core Principle
-
-**Pass state through slots.** Composite components distribute state and handlers via the slot system, keeping state flow explicit and customizable.
-
-## Guidelines
-
-### 1. State Distribution
-
-**Always pass state/handlers via slots:**
-
-```tsx
-import { useSelectState } from '@react-stately/select';
-import { useSelect } from '@react-aria/select';
-import { useRef } from 'react';
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps } = useSelect(props, state, triggerRef);
-
-  // useProps is required for slots to work
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  // Data attributes expose state/props for debugging/styling
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  // Pass state handlers via slots - withSlots merges automatically
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: {
-          ...triggerProps,
-          ref: triggerRef
-        },
-        list: {
-          ...menuProps,
-          selectedKeys: state.selectedKeys,
-          onSelectionChange: state.setSelectedKeys
-        }
-      }}
-    />
-  );
-});
-```
-
-**For state needed deep in tree (not direct slot children), extend Box context `env`:**
-
-```tsx
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-import { Box } from '@bento/box';
-import { useContext } from 'react';
-
-const { props: processedProps } = useProps(props, {
-  isInvalid: state.isInvalid,
-  isOpen: state.isOpen,
-  selectedKeys: state.selectedKeys
-});
-
-const dataAttributes = useDataAttributes({
-  invalid: state.isInvalid,
-  open: state.isOpen
-});
-
-const boxContext = useContext(Box);
-const enhancedContext = {
-  ...boxContext,
-  env: { ...boxContext.env, selectState: state }
-};
-return (
-  <Box.Provider value={enhancedContext}>
-    <Container {...processedProps} {...dataAttributes}>...</Container>
-  </Box.Provider>
-);
-```
-
-**Do not create separate component contexts** - they hide state flow and break the slot-based model.
-
-### 2. Choosing Primitives
-
-**Use Container when:**
-- Component needs polymorphic rendering (`as` prop)
-- Component exposes internal structure via slots
-- Component accepts arbitrary HTML attributes
-
-**Use raw HTML when:**
-- No internal structure to customize
-- Always renders same element
-- Simple leaf component
-
-**Use Box when:**
-- Managing environment/component replacement
-- Providing root-level infrastructure
-
-Most composition should use Container.
-
-### 3. Slot Naming
-
-**Name by semantic purpose, not implementation:**
-
-✅ Good: `trigger`, `content`, `label`, `description`, `errorMessage`
-❌ Avoid: `button`, `div`, `wrapper`
-
-**For nested slots, use dot-separated namespaces:**
-- `trigger` - Top-level trigger
-- `trigger.label` - Text inside trigger
-- `trigger.icon` - Icon inside trigger
-- `popover.list` - ListBox inside popover
-
-**Common slot names:**
-- `root` - Top-level container
-- `trigger` - Activator element
-- `content` - Main content area
-- `label` - Accessible label
-- `description` - Descriptive text
-- `errorMessage` - Error feedback
-- `icon` - Visual icon
-- `header` / `footer` - Section containers
-
-### 4. Component Structure
-
-**Pattern 1: Logic-only (no wrapper element)**
-
-```tsx
-import { useSelectState } from '@react-stately/select';
-import { useSelect } from '@react-aria/select';
-import { useRef } from 'react';
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps } = useSelect(props, state, triggerRef);
-
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  // Pass state handlers via slots - withSlots merges with consumer slots automatically
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        list: { ...menuProps, selectedKeys: state.selectedKeys, onSelectionChange: state.setSelectedKeys }
-      }}
-    />
-  );
-});
-```
-
-**Pattern 2: With wrapper element**
-
-```tsx
-import { useSelectState } from '@react-stately/select';
-import { useSelect } from '@react-aria/select';
-import { useRef } from 'react';
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps } = useSelect(props, state, triggerRef);
-
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  // Pass state handlers via slots - withSlots merges with consumer slots automatically
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        list: { ...menuProps, selectedKeys: state.selectedKeys, onSelectionChange: state.setSelectedKeys }
-      }}
-    />
-  );
-});
-```
-
-### 5. Logic Distribution
-
-**Parent component (composite):**
-- Creates state
-- Passes handlers via slots
-- Manages ARIA relationships
-
-**Child primitives:**
-- Handle their own behavior (press, selection, keyboard nav)
-- Receive state/handlers via slots
-- Manage their own accessibility attributes
-
-### 6. Conditional Rendering
-
-**Multiple patterns for conditional rendering:**
-
-#### Pattern 1: Slots set to null
-
-Slots can be conditionally set to `null` to prevent rendering:
-
-```tsx
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps, descriptionProps, errorMessageProps } = useSelect(props, state, triggerRef);
-
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        list: { ...menuProps, selectedKeys: state.selectedKeys, onSelectionChange: state.setSelectedKeys },
-        description: descriptionProps,
-        errorMessage: state.isInvalid ? errorMessageProps : null // null = don't render
-      }}
-    />
-  );
-});
-
-// Usage - consumers provide children, component controls via slots
-<Select>
-  <Button slot="trigger">
-    <Text slot="value">Select an option</Text>
-  </Button>
-  <Popover slot="popover">
-    <ListBox slot="list">
-      <ListBoxItem>Option 1</ListBoxItem>
-    </ListBox>
-  </Popover>
-  <Text slot="description">Choose an option</Text>
-  <Text slot="errorMessage">Please select a value</Text>
-</Select>
-```
-
-#### Pattern 2: Function slots with conditional logic
-
-Function slots can conditionally render based on state:
-
-```tsx
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps, errorMessageProps } = useSelect(props, state, triggerRef);
-
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        list: { ...menuProps, selectedKeys: state.selectedKeys, onSelectionChange: state.setSelectedKeys },
-        errorMessage: ({ original, props: slotProps }) =>
-          state.isInvalid ? <Text {...slotProps} {...errorMessageProps}>{original}</Text> : null
-      }}
-    />
-  );
-});
-```
-
-#### Pattern 3: Render props via children
-
-Children can be a function that receives state/props. `useProps` automatically handles render props:
-
-```tsx
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps } = useSelect(props, state, triggerRef);
-
-  // Pass state to useProps - it automatically processes render props (including children)
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        list: { ...menuProps, selectedKeys: state.selectedKeys, onSelectionChange: state.setSelectedKeys }
-      }}
-    />
-  );
-});
-
-// Usage - children function automatically receives state via useProps
-<Select>
-  {({ isInvalid, isOpen }) => (
-    <>
-      <Button slot="trigger">
-        <Text slot="value">Select an option</Text>
-      </Button>
-      <Popover slot="popover">
-        <ListBox slot="list">
-          <ListBoxItem>Option 1</ListBoxItem>
-        </ListBox>
-      </Popover>
-      <Text slot="description">Choose an option</Text>
-      {isInvalid && <Text slot="errorMessage">Please select a value</Text>}
-    </>
-  )}
-</Select>
-```
-
-#### Pattern 4: Render props via props
-
-Any prop can be a render function that receives state. `useProps` automatically processes render props:
-
-```tsx
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-
-export const Select = withSlots('BentoSelect', function Select(props) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps, descriptionProps, errorMessageProps } = useSelect(props, state, triggerRef);
-
-  // useProps automatically processes render props (including description, errorMessage, etc.)
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        list: { ...menuProps, selectedKeys: state.selectedKeys, onSelectionChange: state.setSelectedKeys }
-      }}
-    >
-      {processedProps.description && (
-        <Text slot="description" {...descriptionProps}>
-          {processedProps.description}
-        </Text>
-      )}
-      {processedProps.errorMessage && (
-        <Text slot="errorMessage" {...errorMessageProps}>
-          {processedProps.errorMessage}
-        </Text>
-      )}
-    </Container>
-  );
-});
-
-// Usage - any prop can be a render function, automatically processed by useProps
-<Select
-  description={({ isOpen }) => isOpen ? "Selecting..." : "Choose an option"}
-  errorMessage={({ isInvalid }) => isInvalid ? "Please select a value" : null}
->
-  {/* ... */}
-</Select>
-```
-
-**Key principle:** Use `null` in slots for simple conditional rendering. Use function slots for complex conditional logic. Use render props (children or prop functions) when consumers need access to state.
-
-### 7. Slot Customization
-
-**Object slots** - merge props:
-```tsx
-<Select slots={{
-  trigger: { className: 'custom', 'aria-label': 'Choose' },
-  'trigger.icon': { name: 'chevron' }
-}} />
-```
-
-**Function slots** - replace component:
-```tsx
-<Select slots={{
-  trigger: ({ props, original }) => (
-    <CustomButton {...props}>{original}</CustomButton>
-  )
-}} />
-```
-
-## Example: Select Component
-
-```tsx
-import { Container } from '@bento/container';
-import { Button } from '@bento/button';
-import { Popover } from '@bento/popover';
-import { ListBox, ListBoxItem } from '@bento/listbox';
-import { Text } from '@bento/text';
-import { withSlots, Slots } from '@bento/slots';
-import { useSelectState } from '@react-stately/select';
-import { useSelect } from '@react-aria/select';
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-import React, { useRef } from 'react';
-
-export interface SelectProps extends Slots {
-  children?: React.ReactNode;
-}
-
-export const Select = withSlots('BentoSelect', function Select(props: SelectProps) {
-  const state = useSelectState(props);
-  const triggerRef = useRef(null);
-  const { triggerProps, menuProps, descriptionProps, errorMessageProps } = useSelect(props, state, triggerRef);
-
-  // useProps is required for slots to work
-  const { props: processedProps } = useProps(props, {
-    isInvalid: state.isInvalid,
-    isOpen: state.isOpen,
-    selectedKeys: state.selectedKeys
-  });
-
-  // Data attributes expose state for debugging/styling
-  const dataAttributes = useDataAttributes({
-    invalid: state.isInvalid,
-    open: state.isOpen
-  });
-
-  // Filter children by slot for conditional rendering
-  const childArray = React.Children.toArray(processedProps.children);
-  const requiredChildren = childArray.filter((child) => {
-    if (!React.isValidElement(child)) return true;
-    const slot = child.props.slot;
-    return slot !== 'description' && slot !== 'errorMessage';
-  });
-
-  const descriptionChild = childArray.find((child) =>
-    React.isValidElement(child) && child.props.slot === 'description'
-  );
-
-  const errorChild = childArray.find((child) =>
-    React.isValidElement(child) && child.props.slot === 'errorMessage'
-  );
-
-  return (
-    <Container
-      {...processedProps}
-      {...dataAttributes}
-      slot="root"
-      slots={{
-        trigger: {
-          ...triggerProps,
-          ref: triggerRef
-        },
-        list: {
-          ...menuProps,
-          selectedKeys: state.selectedKeys,
-          onSelectionChange: state.setSelectedKeys
-        },
-        description: { ...descriptionProps },
-        errorMessage: { ...errorMessageProps }
-      }}
-    >
-      {requiredChildren}
-
-      {/* Component controls IF these render based on state */}
-      {descriptionChild && (
-        <Container slot="description">
-          {descriptionChild}
-        </Container>
-      )}
-
-      {state.isInvalid && errorChild && (
-        <Container slot="errorMessage">
-          {errorChild}
-        </Container>
-      )}
-    </Container>
-  );
-});
-
-// Usage - consumers provide everything as children, component controls visibility
-<Select>
-  <Button slot="trigger">
-    <Text slot="value">Select an option</Text>
-  </Button>
-  <Popover slot="popover">
-    <ListBox slot="list">
-      <ListBoxItem>Option 1</ListBoxItem>
-      <ListBoxItem>Option 2</ListBoxItem>
-    </ListBox>
-  </Popover>
-  <Text slot="description">Choose one option</Text>
-  <Text slot="errorMessage">Please select a value</Text>
-</Select>
-
-// Component shows errorMessage only when state.isInvalid is true
-// Consumers customize via slots
-<Select slots={{
-  description: { className: 'custom-help' },
-  errorMessage: { className: 'custom-error' }
-}}>
-  {/* ... */}
-</Select>
-```

-## Decision Checklist
-
-When building a composite component:
-
-- [ ] What state/handlers need to be passed to children?
-- [ ] Are they being passed via slots? (they should be)
-- [ ] Does component need a wrapper element?
-- [ ] Which slots are required vs optional?
-- [ ] What are the semantic slot names?
-- [ ] What ARIA relationships need to be established?
-- [ ] How should focus be managed?

-# Overlay
-
-## Purpose
-
-The Overlay primitive serves as a foundational building block for creating layered UI experiences where content appears above the main application view. It provides the core backdrop functionality that supports various overlay-based patterns such as modals, dialogs, drawers, and loading indicators.
-
-The Overlay primitive addresses several key scenarios:
-
-- Displaying content that requires immediate user attention or action
-- Creating focused interaction spaces that temporarily obscure the main content
-- Supporting mobile-first patterns like drawers, sheets, and action menus
-- Enabling rich compositional patterns through layering of UI elements
-
-This primitive will typically be consumed by:
-- Application developers building modal interfaces or drawers
-- Component authors creating specialized dialog components
-- Teams building loading indicators or notification systems
-- Any UI pattern requiring a visual layer between content and application
-
-### Unique Attributes
-
-The Overlay primitive differs from similar components in these key ways:
-
-- **Pure foundation**: Unlike most dialog components that combine multiple concerns, the Overlay provides only the backdrop and layering functionality, allowing maximum composition flexibility
-- **Layering management**: Built-in support for handling multiple overlays with proper stacking context and accessibility
-- **Focus management**: Integrated focus trapping capabilities that follow WAI-ARIA best practices
-- **Scroll locking**: Cross-browser scroll management that prevents background content scrolling
-- **Animation support**: First-class support for entrance/exit animations and transitions
-
-## Primitive Composition
-
-The Overlay primitive composes several standalone reusable primitives, maximizing code sharing across the Bento ecosystem:
-
-### Core Primitive Packages (New)
-Each primitive will be its own package following Bento's architecture:
-
-- **@bento/layer-stack**: Manages stacking order for all layered UI elements
-- **@bento/portal**: Handles DOM rendering placement
-- **@bento/focus-scope**: Contains keyboard focus within a boundary
-- **@bento/scroll-lock**: Prevents background scrolling
-- **@bento/visually-hidden**: Provides screen reader only content
-- **@bento/dismiss-button**: Accessible dismiss functionality
-
-### Overlay Components
-- **OverlayRoot**: State container that manages overlay visibility
-- **OverlayBackdrop**: Visual backdrop that sits behind content
-- **OverlayContent**: Container for overlay content with proper layering and focus handling
-- **OverlayTrigger**: Element that triggers the overlay
-- **OverlayClose**: Button for dismissing the overlay
-
-### React Aria Integration
-All primitives build directly upon React Aria's accessibility-focused hooks:
-- **useModalOverlay**: For backdrop and modal behavior
-- **useFocusScope**: For focus containment
-- **usePreventScroll**: For scroll locking
-- **useOverlayTrigger**: For trigger elements
-- **useOverlay**: For core overlay behavior
-
-## Implementation Patterns
-
-| Concept             | Implementation                                               |
-|---------------------|--------------------------------------------------------------|
-| React Aria          | useModalOverlay, useFocusScope, useOverlayTrigger, useOverlay |
-| Slots               | withSlots for component customization                        |
-| Render Props        | Support for className and style render props with meta object |
-| data-* Attributes   | data-state, data-open, data-animated, data-placement         |
-| data-override       | Used when user customizes backdrop or content behavior       |
-| data-version        | Dev-only attribute for version tracking                      |
-| Composability       | Support for nested content, multiple overlays, context providers |
-
-## Internal Structure & Reuse Potential
-
-Each primitive is designed for maximum reusability across the Bento ecosystem:
-
-### @bento/layer-stack
-
-The LayerStack primitive provides a generalized system for managing any kind of layered UI element, not just overlays. This enables consistent stacking behavior, focus management, and accessibility across different UI patterns.
-
-```jsx

-  }
-  return context;
-};
-
-export const Provider = withSlots('BentoLayerProvider', function LayerProvider(args) {
-  const [props, apply] = useRenderProps(args);
-  const { children } = props;
-  const [layers, setLayers] = useState([]);
-
-  // Register a new layer with optional type and configuration
-  const register = useCallback((id, options = {}) => {

-    const newLayer = { id, type, ...options };
-
-    setLayers(prev => {

-      const sameTypeMax = Math.max(
-        ...prev
-          .filter(layer => layer.type === type)
-          .map(layer => layer.zIndex || 0),
-        0
-      );
-
-      // Base z-index depends on layer type
-      const baseIndex = {
-        tooltip: 600,
-        popover: 700,
-        dropdown: 800,

-        toast: 1200,
-        alert: 1300
-      }[type] || 500;
-
-      // Calculate new z-index
-      const zIndex = sameTypeMax > 0
-        ? sameTypeMax + 10
-        : baseIndex;
-
-      return [...prev, { ...newLayer, zIndex }];
-    });

-            currentLayers[currentLayers.length - 1].id === id,
-          isTopmostOfType: currentLayers.filter(l => l.type === type).length > 0 &&
-            currentLayers.filter(l => l.type === type).slice(-1)[0].id === id
-        };
-      }
-    };
-  }, [layers]);
-
-  // Unregister a layer
-  const unregister = useCallback((id) => {
-    const index = layers.findIndex(layer => layer.id === id);
-    if (index >= 0) {
-      const wasTopmost = index === layers.length - 1;
-      const type = layers[index].type;
-
-      setLayers(prev => prev.filter(layer => layer.id !== id));
-
-      // Return the next layer that should receive focus
-      if (wasTopmost && layers.length > 1) {
-        // Find the next topmost layer of the same type, or any type if none
-        const sameTypeLayer = [...layers]
-          .filter(layer => layer.id !== id && layer.type === type)
-          .pop();
-
-        if (sameTypeLayer) return sameTypeLayer.id;
-
-        // Return the overall topmost layer
-        return layers[layers.length - 2].id;
-      }
-    }
-    return null;
-  }, [layers]);
-
-  // Get the topmost layer, optionally filtered by type
-  const getTopmost = useCallback((type) => {
-    const filteredLayers = type
-      ? layers.filter(layer => layer.type === type)
-      : layers;
-
-    return filteredLayers.length > 0
-      ? filteredLayers[filteredLayers.length - 1].id
-      : null;
-  }, [layers]);
-
-  const value = useMemo(() => ({
-    register,
-    unregister,
-    getTopmost,
-    isTopmost: (id, options = {}) => {
-      const { ofType = false } = options;

-  }), [register, unregister, getTopmost, layers]);
-
-  return (
-    <LayerContext.Provider value={value}>

-
-## React Aria Integration
-
-### Why React Aria?
-
-After extensive research of different overlay implementations, React Aria stands out as the optimal foundation for several reasons:
-
-1. **Accessibility excellence**: React Aria is built from the ground up with accessibility as the primary focus, ensuring WCAG compliance.
-
-2. **Comprehensive feature set**: React Aria provides a complete solution for overlay functionality:
-   - Focus management with `useFocusScope`
-   - Scroll locking with `usePreventScroll`
-   - Backdrop interaction with `useModalOverlay`
-   - Trigger management with `useOverlayTrigger`
-
-3. **Battle-tested in production**: Used extensively in Adobe's product ecosystem, ensuring robust performance in real-world applications.
-
-4. **Excellent mobile support**: Handles complex mobile edge cases that other libraries miss, including iOS Safari scroll handling.
-
-5. **Active maintenance**: Regular updates and community support ensure the library stays current with browser changes and accessibility standards.
-
-### Comparative Analysis
-
-We evaluated several libraries for overlay implementation:
-
-| Library | Strengths | Weaknesses | Focus Management | Multiple Overlay Support |
-|---------|-----------|------------|------------------|--------------------------|
-| React Aria | Exceptional a11y, robust focus management, strong mobile support | Less composable API | FocusScope component with complete trapping | Overlay container system |
-| Radix UI | Highly composable API, excellent animation support | Some mobile edge cases | Dialog-specific focus handling | Built-in dialog stack |
-| AriaKit | Flexible API, excellent composition | More complex API | FocusTrap component | Store-based dialog state |
-| Headless UI | Simplicity, good animation integration | Less flexible | Dialog-specific focus handling | Limited |
-| Material UI | Performance optimizations, comprehensive features | Less headless, more opinionated | Uses custom FocusTrap | ModalManager utility |
-
-React Aria provides the strongest foundation for accessibility and mobile support, which are top priorities. We'll enhance it with Bento's composition model and additional features from other libraries where appropriate.
-
-## Multiple Overlay Management
-
-A key consideration is handling multiple active overlays simultaneously. Our research across implementations revealed several approaches:
-
-### Stacking and Focus Management Challenges
-
-When multiple overlays are active, three aspects must be managed:
-
-1. **Visual stacking**: Which overlay appears on top
-2. **Keyboard focus**: Which overlay receives focus
-3. **Interaction boundaries**: How interactions propagate between layers
-
-### ARIA Requirements for Multiple Overlays
-
-For proper accessibility:
-- Only the topmost modal overlay should have `aria-modal="true"`
-- Lower overlays should receive `aria-hidden="true"`
-- Focus should transfer between overlays in a predictable manner matching the visual hierarchy
-
-### Implementation Approaches
-
-Different libraries handle multiple overlays in different ways:
-
-- **Radix UI**: Uses a global dialog stack to track open dialogs
-- **AriaKit**: Uses a dialog store to manage state and explicit ordering
-- **React Aria**: Uses overlay containers with built-in stacking
-- **MUI**: Uses a dedicated ModalManager to handle multiple modals
-
-Our `@bento/layer-stack` primitive incorporates the best aspects of these approaches while maintaining full compatibility with React Aria:
-
-```jsx
-function OverlayProvider({ children }) {
-  // Use React Aria's overlay container as the foundation
-  const ref = useRef();
-  const { overlayContainerRef } = useOverlayContainer();
-
-  useEffect(() => {
-    // Connect our ref to React Aria's overlay container
-    if (ref.current) {
-      overlayContainerRef.current = ref.current;
-    }
-  }, [overlayContainerRef]);
-
-  // Add Bento-specific overlay stack management
-  const [overlayStack, setOverlayStack] = useState([]);
-
-  // Implementation details...
-
-  return (
-    <LayerContext.Provider value={value}>
-      {children}
-      <div ref={ref} />
-    </LayerContext.Provider>
-  );
-}
-```
-
-## Focus Management
-
-Focus management is consistently the most critical and complex aspect of overlay implementations. Based on our research, we identified these key requirements:
-
-1. **Focus trapping**: Prevents tabbing outside the overlay while it's open
-2. **Initial focus control**: Allows specifying which element receives focus when opened
-3. **Return focus**: Returns focus to the trigger element when closed
-4. **Focus stack**: Manages focus between multiple overlays
-
-React Aria's FocusScope is the most robust solution we evaluated, handling edge cases like:
-- Browser extensions that inject focusable elements
-- Shadow DOM boundaries
-- Dynamic content changes
-- Screen reader navigation
-
-Our `@bento/focus-scope` primitive preserves these capabilities while adapting to Bento's patterns.
-
-## Animation Support
-
-Animation is a crucial part of a good overlay experience. Our research identified several approaches:
-
-1. **CSS-based animations**: Using data attributes for state-driven animations
-2. **Component-based animations**: Providing animation components for common patterns
-3. **Hook-based animations**: Exposing animation state for custom animations
-
-Different libraries handle animations in different ways:
-- **Radix UI**: Uses data attributes (`data-state`, `data-side`, etc.) for CSS animations
-- **Chakra UI**: Provides transition components for common animations
-- **Material UI**: Offers dedicated transition components
-- **AriaKit**: Supports CSS transitions and library integration
-
-Our approach leverages data attributes for maximum flexibility:
-
-```jsx
-<Overlay.Content
-  className={({ state }) => {
-    if (state.open && state.animated) return styles.contentAnimateIn;
-    if (!state.open && state.animated) return styles.contentAnimateOut;
-    return styles.content;
-  }}
->
-  Content with CSS animations
-</Overlay.Content>
-```
-
-## Mobile Considerations
-
-Mobile devices present unique challenges for overlays:
-
-1. **Touch interactions**: Mobile-friendly dismissal and interaction patterns
-2. **Virtual keyboard handling**: Adjusting for keyboard appearance that may cover content
-3. **Safe areas**: Respecting device-specific safe areas (notches, home indicators)
-4. **Scroll management**: Preventing background content scroll without breaking overlay scrolling
-
-Specific issues identified in our research:
-- iOS Safari has unique scroll behavior requiring special handling
-- Android Chrome can have focus-related scrolling issues
-- Virtual keyboards can push content out of view
-
-React Aria handles most of these issues effectively, particularly with its `usePreventScroll` hook that properly manages iOS Safari edge cases.
-
-## Scrolling Behavior
-
-Scroll management is a complex aspect of overlay implementation. Our research revealed several approaches:
-
-1. **Body overflow technique**: Setting `overflow: hidden` on the document body
-2. **Position fixed technique**: Using `position: fixed` with saved scroll position
-3. **Inert attribute**: Using the `inert` attribute on background elements (limited browser support)
-
-React Aria's `usePreventScroll` hook provides the most robust solution:
-
-```javascript
-// Excerpt from React Aria's implementation
-useLayoutEffect(() => {
-  if (!isDisabled && isMounted.current) {
-    activeCount++;
-    if (activeCount === 1) {
-      // Save the initial body style
-      originalStyles.current = {
-        overflow: document.body.style.overflow,
-        paddingRight: document.body.style.paddingRight
-      };
-
-      // Get the scrollbar width
-      let scrollbarWidth = window.innerWidth - document.documentElement.clientWidth;
-
-      // Add padding to prevent layout shift
-      if (scrollbarWidth > 0) {
-        document.body.style.paddingRight = `${scrollbarWidth}px`;
-      }
-
-      // Prevent scrolling
-      document.body.style.overflow = 'hidden';
-    }
-
-    return () => {
-      activeCount--;
-      if (activeCount === 0) {
-        // Restore the initial body style
-        document.body.style.overflow = originalStyles.current.overflow;
-        document.body.style.paddingRight = originalStyles.current.paddingRight;
-      }
-    };
-  }
-}, [isDisabled]);
-```
-
-## Performance Considerations
-
-Performance is critical for overlays, especially on mobile devices. Our research identified several optimization opportunities:
-
-1. **Conditional rendering**: Only mount components when they're visible
-2. **Memoization**: Use React.memo and useMemo for complex overlay content
-3. **Animation optimization**: Animate only transform and opacity properties when possible
-4. **Lazy loading**: Support code-splitting for heavy overlay content
-5. **Cleanup**: Ensure proper removal of event listeners and cleanup of effects
-
-Implementation examples for performance optimization:
-
-```jsx
-// Conditional rendering
-function OptimizedOverlay() {
-  const [open, setOpen] = useState(false);
-
-  // Only render overlay content when open
-  return (
-    <>
-      <button onClick={() => setOpen(true)}>Open</button>
-      {open && (
-        <Overlay.Root>
-          <Overlay.Content>
-            {/* Content here */}
-          </Overlay.Content>
-        </Overlay.Root>
-      )}
-    </>
-  );
-}
-
-// Memoization for expensive content
-const MemoizedOverlayContent = React.memo(function OverlayContent() {
-  // Complex content here
-  return <div>{/* ... */}</div>;
-});
-```
-
-## Accessibility Highlights
-
-The Overlay primitive inherits React Aria's excellent accessibility features:
-
-- **ARIA roles:** Automatically applies `role="dialog"` or `role="alertdialog"` when appropriate
-- **Modal state:** Uses `aria-modal="true"` for modal overlays
-- **Focus management:** Implements proper focus trapping via the FocusScope primitive
-- **Keyboard support:**
-  - Escape key to dismiss
-  - Tab navigation contained within the overlay
-  - Return focus to trigger element on close
-- **Screen reader announcements** for overlay state changes
-- **Proper handling of focus order** with multiple overlays
-
-For mobile accessibility specifically:
-- Touch targets follow accessibility guidelines (minimum 44×44px)
-- Screen reader gestures are properly supported
-- Visible focus indicators are maintained for keyboard users
-
-## Internationalization, RTL, and Mobile Considerations
-
-The Overlay primitive is designed to work across different languages and layouts:
-
-- **RTL support:** The overlay positioning and animations work correctly in right-to-left layouts
-- **Mobile considerations:**
-  - Larger touch targets for mobile interactions
-  - Special handling for iOS Safari to prevent background content scrolling
-  - Support for mobile gestures (swipe to dismiss)
-  - Adjustments for virtual keyboard appearance
-  - Responsive sizing and positioning
-
-- **Internationalization:** The component handles text expansion from different languages by using flexible layouts

-    </Portal>
-  );
-}
-```
-
-## Competitive Research
-
-We conducted comprehensive research across major component libraries to identify the best approaches to overlay implementation:
-
-### React Aria
-
-React Aria provides a robust set of hooks for building accessible overlays:
-
-- **useOverlay**: Manages ARIA attributes and keyboard interactions
-- **useModalOverlay**: Adds modal-specific behaviors like backdrop interaction
-- **useFocusScope**: Handles focus containment
-- **usePreventScroll**: Manages scroll locking with excellent cross-browser support
-- **useOverlayPosition**: Supports positioning relative to trigger elements
-- **useOverlayTrigger**: Connects trigger elements to overlays
-
-React Aria excels at accessibility but has a more imperative API that requires additional work to fit into Bento's composable component model.
-
-### Radix UI
-
-Radix UI offers a highly composable dialog component:
-
-```jsx
-// Radix UI approach
-<Dialog.Root>
-  <Dialog.Trigger />
-  <Dialog.Portal>
-    <Dialog.Overlay />
-    <Dialog.Content>
-      <Dialog.Title />
-      <Dialog.Description />
-      <Dialog.Close />
-    </Dialog.Content>
-  </Dialog.Portal>
-</Dialog.Root>
-```
-
-Strengths:
-- Excellent composition model
-- Good animation support via data attributes
-- Solid accessibility
-
-Weaknesses:
-- Some mobile edge cases
-- Occasional focus management issues in complex scenarios
-
-### AriaKit
-
-AriaKit provides a flexible, store-based approach:
-
-```jsx
-// AriaKit approach
-const dialog = useDialogStore();
-
-<Dialog store={dialog}>
-  <DialogHeading>Title</DialogHeading>
-  <DialogDescription>Description</DialogDescription>
-  <div>Content</div>
-  <DialogDismiss>Close</DialogDismiss>
-</Dialog>
-```
-
-Strengths:
-- Powerful, flexible API
-- Excellent composition
-- Strong accessibility
-
-Weaknesses:
-- More complex API with steeper learning curve
-- Less direct React Aria integration
-
-### Headless UI
-
-Headless UI offers a simpler approach with good animation integration:
-
-```jsx
-// Headless UI approach
-<Transition show={isOpen}>
-  <Dialog onClose={setIsOpen}>
-    <Dialog.Overlay />
-    <Dialog.Title>Title</Dialog.Title>
-    <Dialog.Description>Description</Dialog.Description>
-    <div>Content</div>
-  </Dialog>
-</Transition>
-```
-
-Strengths:
-- Simplicity
-- Good animation integration
-- Solid accessibility
-
-Weaknesses:
-- Less flexible
-- Fewer customization options
-
-### Material UI
-
-Material UI provides a comprehensive modal implementation:
-
-```jsx
-// Material UI approach
-<Modal
-  open={open}
-  onClose={handleClose}
-  aria-labelledby="modal-title"
-  aria-describedby="modal-description"
->
-  <Box>
-    <h2 id="modal-title">Title</h2>
-    <p id="modal-description">Description</p>
-  </Box>
-</Modal>
-```
-
-Strengths:
-- Comprehensive features
-- Good performance optimizations
-- Built-in transitions
-
-Weaknesses:
-- More opinionated
-- Less headless
-- Less compositional
-
-## UX Best Practices for Multiple Overlays
-
-From a user experience perspective, multiple active overlays require careful consideration:
-
-1. **Visual hierarchy**: Each new overlay should clearly appear above previous ones
-2. **Contextual relationship**: Related overlays should maintain visual connection
-3. **Consistent dismissal pattern**: Users should be able to dismiss overlays in reverse order of appearance
-
-Our research identified several effective patterns:
-
-- **Overlay groups**: Supporting parent-child relationships between overlays
-- **Contextual positioning**: Positioning new overlays relative to their trigger elements
-- **Backdrop variation**: Using different backdrop opacities or colors to indicate hierarchy
-- **Animation coordination**: Coordinating enter/exit animations between overlays
-
-These patterns can be implemented using our proposed primitives:
-
-```jsx
-// Managing parent-child overlay relationships
-<Overlay.Root>
-  <Overlay.Trigger>Open parent</Overlay.Trigger>
-  <Overlay.Content>
-    <Overlay.Root>
-      <Overlay.Trigger>Open child</Overlay.Trigger>
-      <Overlay.Content>
-        Child overlay content
-      </Overlay.Content>
-    </Overlay.Root>
-  </Overlay.Content>
-</Overlay.Root>
-```
-
-## Animation Capabilities
-
-All modern overlay implementations support animations, with varying approaches:
-
-- **CSS-based**: Using data attributes for state-driven animations
-- **Component-based**: Providing animation components for common patterns
-- **Hook-based**: Exposing animation state for custom animation
-
-Our approach leverages data attributes for maximum flexibility while supporting integration with animation libraries:
-
-```css
-/* CSS-based animation example */
-.overlay[data-state="open"] {
-  animation: fadeIn 200ms ease;
-}
-
-.overlay[data-state="closed"] {
-  animation: fadeOut 200ms ease;
-}
-```
-
-This approach works well with:
-- Pure CSS animations
-- CSS-in-JS libraries
-- Animation libraries like Framer Motion
-
-## Z-index Management
-
-Stacking context and z-index management require a systematic approach, which our LayerStack primitive provides:
-
-- **Established z-index scale**: Predefined ranges for different UI layer types
-- **Dynamic z-index calculation**: Based on layer type and existing layers
-- **Proper stacking of multiple layers**: Ensuring correct visual hierarchy
-- **Integration with React Aria's overlay container**: For maximum compatibility
-
-The LayerStack primitive handles these concerns automatically, providing a consistent approach across all Bento components.
-
-## Conclusion
-
-By creating a suite of generalized primitives as individual packages, the Bento Overlay component can leverage reusable building blocks that serve multiple UI patterns. This approach:
-
-1. **Maximizes reusability** across the component system
-2. **Follows Bento's established architecture** of separate primitive packages
-3. **Leverages React Aria** for best-in-class accessibility
-4. **Enables consistent behavior** across different UI patterns
-5. **Promotes compositional flexibility** for developers
-
-The resulting Overlay component will be built on a solid foundation of primitives that can be used and maintained independently, making the entire Bento system more robust, consistent, and developer-friendly.

-# Overlay Component PDR
-
-## Purpose
-
-The Overlay component serves as the primary building block for creating layered UI experiences where content appears above the main application view. It provides a complete, accessible foundation for modal dialogs, drawers, fullscreen overlays, and other patterns requiring content to appear on top of the page.
-
-**For micro-frontend architectures**, Overlay integrates with Layer Orchestration (see `layer-orchestration.mdx`) to coordinate layers across independent JavaScript bundles **without requiring a host application**. Using a DOM-based registry, MFEs self-organize to ensure proper z-index management, priority resolution, and ARIA coordination when multiple MFEs compete for screen space.
-
-The Overlay component addresses several key scenarios:
-
-- **Modal dialogs**: Displaying content that requires immediate user attention
-- **Drawers and sheets**: Side panels or bottom sheets common in mobile interfaces
-- **Loading states**: Fullscreen loading indicators that block interaction
-- **Image viewers**: Lightbox-style image viewing experiences
-- **Onboarding flows**: Step-by-step tutorials that overlay the application
-
-This component will be consumed by:
-- Application developers building modal interfaces
-- Design system teams creating specialized dialog components
-- Product teams implementing mobile-first drawer patterns
-- Any UI pattern requiring layered content with focus management
-
-### Unique Attributes
-
-The Overlay component differs from simple portal+backdrop combinations in these key ways:
-
-- **Complete accessibility**: Built on React Aria's `useModalOverlay` with proper ARIA attributes and focus management
-- **Composable architecture**: Combines Portal, Underlay, and FocusLock primitives through Bento's slot system
-- **Flexible rendering**: Supports both modal (blocking) and non-modal (non-blocking) overlays
-- **Scroll management**: Integrates with React Aria's `usePreventScroll` to handle background scrolling
-- **Mobile-optimized**: Handles iOS Safari scroll quirks and mobile gesture patterns
-- **Bento patterns**: Built with `withSlots`, `useProps`, and `useDataAttributes` for ecosystem consistency
-
-## Primitive Composition
-
-The Overlay component composes several Bento primitives and systems:
-
-1. **`Portal`** (@bento/portal): Renders overlay content outside parent DOM hierarchy
-2. **`Underlay`** (@bento/underlay): Provides backdrop with click-to-dismiss behavior
-3. **`FocusLock`** (@bento/focus-lock): Manages focus containment within overlay
-4. **`Container`** (@bento/container): Polymorphic container for overlay content
-5. **`useLayerOrchestration`** (@bento/layer-orchestration): Registers layer in DOM registry for multi-MFE coordination (optional)
-6. **`useModalOverlay`** (React Aria): Provides modal overlay behavior and accessibility
-7. **`useModal`** (React Aria): Manages aria-hidden coordination
-8. **`usePreventScroll`** (React Aria): Prevents background scrolling when overlay is open
-9. **`useDialog`** (React Aria): Provides dialog ARIA attributes when needed
-10. **`useOverlayTriggerState`** (React Aria): State management for overlays
-11. **`withSlots`**: Bento's slot system for composition
-12. **`useProps`**: Bento's prop handling with state exposure
-13. **`useDataAttributes`**: Exposes state as data attributes
-

-
-**Key Points:**
-
-1. **Layer Orchestration Integration**: When `mfeId` is provided, registers layer in DOM registry for cross-MFE coordination
-2. **Priority-based stacking**: Uses numeric `priority` for version-agnostic coordination
-3. **Orchestrated z-index**: Calculated from DOM registry by all bundles
-4. **Orchestrated ARIA**: Calculated from DOM registry for multi-MFE scenarios
-5. **React ARIA fallback**: When no `mfeId`, uses React ARIA's OverlayProvider pattern
-6. **Backward compatible**: Works with or without orchestration
-7. **No host needed**: MFEs self-organize via DOM without host application

-## Implementation Patterns
-
-| Concept             | Implementation                                               |
-|---------------------|--------------------------------------------------------------|
-| React Aria          | useModalOverlay, usePreventScroll, useDialog, useOverlayTrigger |
-| Slots               | withSlots for customizing underlay, content, and structure   |
-| Render Props        | className and style as functions with state object           |
-| data-* Attributes   | data-open, data-modal, data-dismissable                      |
-| data-version        | Dev-only attribute for version tracking                      |
-| Composability       | Supports nested overlays, custom containers, slot overrides  |
-
-## Internal Structure & Reuse Potential
-
-The Overlay component is designed as a coordinator that brings together focused primitives:
-
-```
-Overlay (state management, coordination)
-├─ Portal (DOM rendering location)
-│  ├─ Underlay (backdrop, click-to-dismiss)
-│  └─ FocusLock (focus containment)
-│     └─ Container (overlay content)
-│        └─ children (user content)
-```
-
-Each piece can be used independently:
-
-- **Portal**: Use alone for tooltips, popovers (no backdrop needed)
-- **Underlay**: Use with custom overlay implementations
-- **FocusLock**: Use for focus trapping without full overlay pattern
-- **Overlay**: Use as complete solution for modal experiences
-
-This separation enables:
-- High reuse of primitives across different patterns
-- Clear separation of concerns (rendering, focus, backdrop, content)
-- Flexibility to compose custom overlay experiences
-- Minimal, focused primitive implementations
-
-## React Aria Integration
-
-The Overlay component leverages multiple React Aria hooks:
-
-### useModalOverlay
-
-Provides core overlay behavior:
-
-```tsx
-const { modalProps, underlayProps } = useModalOverlay(props, state, ref);
-```
-
-Benefits:
-- ARIA attributes for modal overlays (`aria-modal="true"`)
-- Click-outside-to-dismiss behavior
-- Escape key handling
-- Proper event handling across devices
-
-### usePreventScroll
-
-Prevents background scrolling while overlay is open:
-
-```tsx
-usePreventScroll({ isDisabled: !isOpen });
-```
-
-Benefits:
-- Cross-browser scroll prevention
-- Handles iOS Safari scroll quirks
-- Preserves scroll position
-- Accounts for scrollbar width to prevent layout shift
-
-### useDialog (optional)
-
-Provides dialog-specific ARIA attributes when overlay contains a dialog:
-
-```tsx
-const { dialogProps, titleProps } = useDialog(props, ref);
-```
-
-Benefits:
-- Proper `role="dialog"` or `role="alertdialog"`
-- Associates title with dialog via `aria-labelledby`
-- Associates description via `aria-describedby`
-
-### useOverlayTrigger (for parent integration)
-
-Not used directly by Overlay, but provided for components that trigger overlays:
-
-```tsx
-const { triggerProps, overlayProps } = useOverlayTrigger(props, state);
-```
-
-This is exported for consumers building trigger+overlay patterns.
-
-## Architecture & Features
-
-### Core Behavior
-
-The Overlay component:
-
-1. **Manages open/closed state**: Controlled or uncontrolled
-2. **Renders via portal**: Content appears at document.body (customizable)
-3. **Shows backdrop**: Optional underlay with click-to-dismiss
-4. **Locks focus**: Traps keyboard focus within overlay content
-5. **Prevents scroll**: Locks background scrolling while open
-6. **Handles dismissal**: Escape key, outside click, programmatic close
-7. **Exposes state**: Via data attributes and render props
-

-### Rendered DOM Structure
-
-```html
-<!-- Portal renders to document.body by default -->
-<div data-portal="true">
-  <!-- Underlay (only when isModal=true) -->
-  <div
-    data-underlay="true"
-    data-dismissable="true"
-    class="overlay-underlay"
-  ></div>
-

-      class="overlay-content"
-    >
-      <!-- User content goes here -->
-    </div>
-  </div>
-</div>
-```
-
-### Controlled vs Uncontrolled
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Heading } from '@bento/heading';
-import { Button } from '@bento/button';
-import { Text } from '@bento/text';
-import { useState } from 'react';
-
-// Controlled - component manages state
-function ControlledExample() {
-  const [isOpen, setIsOpen] = useState(false);
-
-  return (
-    <Container>
-      <Button onPress={() => setIsOpen(true)}>
-        <Text>Open</Text>
-      </Button>
-      <Overlay isOpen={isOpen} onOpenChange={setIsOpen}>
-        <Container>
-          <Heading level={2}>Modal Content</Heading>
-          <Button onPress={() => setIsOpen(false)}>
-            <Text>Close</Text>
-          </Button>
-        </Container>
-      </Overlay>
-    </Container>
-  );
-}
-
-// Uncontrolled - Overlay manages state internally
-function UncontrolledExample() {
-  return (
-    <Overlay defaultOpen={false}>
-      {({ close }) => (
-        <Container>
-          <Heading level={2}>Modal Content</Heading>
-          <Button onPress={close}>
-            <Text>Close</Text>
-          </Button>
-        </Container>
-      )}
-    </Overlay>
-  );
-}

-### Slot Map
-
-| Slot Name    | Description                          | Required | Default Fallback |
-|--------------|--------------------------------------|----------|------------------|
-| `underlay`   | Backdrop/underlay element            | No       | Yes (when modal) |
-| `content`    | Main overlay content container       | No       | Yes              |
-| `focus-lock` | Focus containment wrapper            | No       | Yes (when modal) |
-
-### State Management
-
-The Overlay uses React Aria's overlay state management pattern:
-
-```tsx
-// Internal state management
-const state = useOverlayTriggerState(props);
-const { isOpen } = state;
-```
-
-This provides:
-- Controlled/uncontrolled state handling
-- Open/close methods
-- State synchronization
-- Event handler composition
-
-### Modal vs Non-Modal
-
-**Modal overlays** (`isModal={true}`, default):
-- Show backdrop/underlay
-- Lock focus within overlay
-- Prevent background scrolling
-- Block background interaction
-- Apply `aria-modal="true"`
-
-**Non-modal overlays** (`isModal={false}`):
-- No backdrop
-- Focus not locked (can tab to background)
-- Background scrolling allowed
-- Background remains interactive
-- No `aria-modal` attribute
-
-Use cases:
-- Modal: Dialogs requiring user action, critical alerts
-- Non-modal: Tooltips, popovers, dropdown menus
-
-## Accessibility Highlights
-
-The Overlay component provides comprehensive accessibility:
-
-### ARIA Attributes
-
-- **`role`**: Defaults to `"dialog"`, can be `"alertdialog"`, `"menu"`, `"listbox"`
-- **`aria-modal`**: Set to `"true"` for modal overlays
-- **`aria-labelledby`**: Associates overlay with labeling element
-- **`aria-describedby`**: Associates overlay with describing element
-- **`aria-label`**: Direct label when no labelledby element exists
-
-### Focus Management
-
-- **Auto-focus**: First focusable element receives focus on open
-- **Focus containment**: Tab/Shift+Tab cycle within overlay (modal only)
-- **Focus restoration**: Focus returns to trigger element on close
-- **Focus visible**: Keyboard focus indicators shown appropriately
-
-### Keyboard Support
-
-- **Escape**: Closes dismissable overlays
-- **Tab**: Cycles focus within modal overlays
-- **Shift+Tab**: Reverse cycles focus within modal overlays
-
-### Screen Reader Support
-
-- **Role announcement**: Screen readers announce dialog role
-- **Modal state**: `aria-modal` hides background from screen readers
-- **Labeling**: Proper label associations for context
-- **Dismissal**: Screen readers can access close mechanisms
-
-## Internationalization, RTL, and Mobile Considerations
-
-### RTL Support
-
-The Overlay is direction-agnostic:
-- Uses logical properties for layout (`inset`, flexbox)
-- Portal rendering is direction-independent
-- Content direction handled by children
-
-### Mobile Considerations
-
-#### Touch Interactions
-
-- **Touch-to-dismiss**: Underlay responds to touch events
-- **Swipe gestures**: Can be added via custom handlers
-- **Pull-to-close**: Supported via custom implementations
-
-#### iOS Safari Handling
-
-React Aria's `usePreventScroll` handles iOS Safari quirks:
-- Prevents rubber-band scrolling
-- Maintains scroll position
-- Handles virtual keyboard appearance
-
-#### Safe Areas
-
-Overlays respect device safe areas via CSS:
-
-```tsx
-<Overlay
-  style={{
-    paddingTop: 'env(safe-area-inset-top)',
-    paddingBottom: 'env(safe-area-inset-bottom)'
-  }}
->
-  {/* content */}
-</Overlay>
-```
-
-#### Mobile Patterns
-
-Common mobile overlay patterns:
-
-- **Bottom sheets**: Overlay from bottom edge
-- **Drawers**: Overlay from side edges
-- **Fullscreen modals**: Cover entire viewport
-
-All supported via styling and slot customization.
-
-### Internationalization
-
-- No text content in component itself
-- ARIA labels provided by consumers in appropriate locale
-- Content direction handled by consumers
-
-## Data Attributes and Slot Map
-
-### Expected `data-*` Attributes
-
-| Attribute            | Description                          | Example Values                      |
-|----------------------|--------------------------------------|-------------------------------------|
-| `data-open`          | Whether overlay is open              | "true" / "false"                    |
-| `data-modal`         | Whether overlay is modal             | "true" / "false"                    |
-| `data-dismissable`   | Whether overlay is dismissable       | "true" / "false"                    |
-| `data-priority`      | Priority level (with orchestrator)   | "critical" / "high" / "normal" / "low" |
-| `data-version`       | Component version (dev only)         | "overlay@1.0"                       |
-
-### Slot Map
-
-| Slot Name    | Description                             | Required | Default Fallback |
-|--------------|-----------------------------------------|----------|------------------|
-| `underlay`   | Backdrop/underlay props                 | No       | Yes (modal only) |
-| `content`    | Main overlay content container props    | No       | Yes              |
-| `focus-lock` | Focus containment wrapper props         | No       | Yes (modal only) |

-## Competitive Research
-
-### React Aria
-
-React Aria provides `useModalOverlay` and related hooks but no component. Our Overlay wraps these hooks in a complete, composable component.
-
-**Key learnings**:
-- Separation of modal vs non-modal is essential
-- Focus management is complex and benefits from proven implementation
-- Scroll prevention needs special handling for iOS
-
-**Reference**: [React Aria useModalOverlay](https://react-spectrum.adobe.com/react-aria/useModalOverlay.html)
-
-### Radix UI Dialog
-
-Radix provides a comprehensive Dialog primitive with excellent composition:
-
-```tsx
-<Dialog.Root>
-  <Dialog.Trigger />
-  <Dialog.Portal>
-    <Dialog.Overlay />
-    <Dialog.Content>
-      <Dialog.Title />
-      <Dialog.Description />
-    </Dialog.Content>
-  </Dialog.Portal>
-</Dialog.Root>
-```
-
-**Key learnings**:
-- Explicit Portal component gives control over rendering
-- Separate Overlay (backdrop) from Content is clearer
-- Trigger integration is valuable for common patterns
-
-**Differences**:
-- Radix uses compound components, Bento uses slots
-- Radix more opinionated about structure
-- Bento more flexible for custom compositions
-
-**Reference**: [Radix Dialog](https://www.radix-ui.com/primitives/docs/components/dialog)
-
-### Headless UI Dialog
-
-Headless UI provides a simpler Dialog component:
-
-```tsx
-<Dialog open={isOpen} onClose={setIsOpen}>
-  <Dialog.Overlay />
-  <Dialog.Panel>
-    <Dialog.Title />
-    <Dialog.Description />
-  </Dialog.Panel>
-</Dialog>
-```
-
-**Key learnings**:
-- Simplicity is valuable for common cases
-- Overlay and Panel separation is intuitive
-- Close handling through onClose prop is straightforward
-
-**Differences**:
-- Headless UI less flexible for advanced composition
-- Bento provides more control via slots
-
-**Reference**: [Headless UI Dialog](https://headlessui.com/react/dialog)
-
-### Chakra UI Modal
-
-Chakra provides a styled Modal component:
-
-```tsx
-<Modal isOpen={isOpen} onClose={onClose}>
-  <ModalOverlay />
-  <ModalContent>
-    <ModalHeader />
-    <ModalBody />
-    <ModalFooter />
-  </ModalContent>
-</Modal>
-```
-
-**Key learnings**:
-- Separate overlay from content container
-- Header/Body/Footer structure for common layouts
-- Size variants for different use cases
-
-**Differences**:
-- Chakra includes styling, Bento is headless
-- Chakra more prescriptive about structure
-
-**Reference**: [Chakra Modal](https://chakra-ui.com/docs/components/modal)
-
-### Material UI Dialog
-
-Material UI provides a comprehensive Dialog:
-
-```tsx
-<Dialog open={open} onClose={handleClose}>
-  <DialogTitle />
-  <DialogContent>
-    <DialogContentText />
-  </DialogContent>
-  <DialogActions />
-</Dialog>
-```
-
-**Key learnings**:
-- Structured content areas (Title, Content, Actions)
-- Transition support built-in
-- Various sizing modes
-
-**Differences**:
-- Material UI very opinionated about styling
-- Bento more primitive and flexible
-
-**Reference**: [Material UI Dialog](https://mui.com/material-ui/react-dialog/)
-
-### Ark UI Dialog
-
-Ark UI (Park UI's headless library) provides similar patterns to Radix:
-
-**Key learnings**:
-- Headless approach aligns with Bento
-- Composition via explicit components
-- Strong accessibility foundation

-Complex applications frequently need to handle multiple overlays simultaneously:
-
-1. **Nested modals**: A confirmation dialog opens from within a settings modal
-2. **Micro-frontend scenarios**: Multiple independent widgets each opening overlays
-3. **Sequential workflows**: Step-by-step wizards with modal confirmations
-4. **Multiple concurrent overlays**: Chat window + notification + modal
-
-### React ARIA's Solution: OverlayProvider
-
-React ARIA provides `OverlayProvider` to manage multiple overlays **within a single React tree/JavaScript bundle**. This works well for single applications but **has limitations for micro-frontends**.
-
-**Limitations with MFEs:**
-- Only works within single React tree
-- Cannot coordinate across independent JavaScript bundles
-- MFEs can't share OverlayProvider context
-- Z-index conflicts between MFEs
-
-### Layer Orchestration: Cross-MFE Solution
-
-For micro-frontend architectures, use **Layer Orchestration** (see `layer-orchestration.mdx`). This is the **recommended approach for multi-MFE applications**.
-
-**Key Innovation:**
-- **No host required**: MFEs self-organize via DOM registry
-- **Version-agnostic**: Works across Bento v1, v2, v3, etc.
-- **Simple protocol**: DOM attributes as source of truth
-- **No leader election**: All bundles are equal
-
-#### How It Works
-
-```tsx
-import { OverlayProvider } from '@react-aria/overlays';
-import { Overlay } from '@bento/overlay';
-
-function App() {
-  return (
-    <OverlayProvider>
-      <YourApp>
-        {/* All Overlays automatically coordinate */}
-        <Modal1 />
-        <Modal2 />
-      </YourApp>
-    </OverlayProvider>
-  );
-}
-```
-
-**OverlayProvider manages:**
-- **Automatic z-index**: Each overlay gets progressively higher z-index
-- **Focus stack**: Only topmost overlay receives focus
-- **ARIA coordination**: Topmost overlay gets `aria-modal="true"`, others get `aria-hidden="true"`
-- **Shared container**: All overlays portal to the same container
-
-### Stacking Behavior
-
-When multiple overlays are open:
-
-**Visual Stack (Top → Bottom):**
-```
-Inner Modal (z-index: 1020, aria-modal="true")
-Inner Modal Backdrop
-Outer Modal (z-index: 1010, aria-hidden="true")
-Outer Modal Backdrop
-Application (aria-hidden="true" when any modal is open)
-```
-
-**Focus Management:**
-1. Focus moves to newest overlay automatically
-2. Escape key closes topmost overlay
-3. When overlay closes, focus returns to previous overlay (if nested) or trigger element
-
-**ARIA Attributes:**
-- Only topmost modal has `aria-modal="true"`
-- Lower modals have `aria-hidden="true"`
-- Application content has `aria-hidden="true"` when any modal is open
-
-### Backdrop Management
-
-**Bento uses multiple backdrops** (one per overlay) for clearer visual hierarchy:
-
-```tsx
-// Each overlay has its own backdrop
-<Overlay isOpen={modal1Open}>
-  {/* Has its own backdrop */}
-</Overlay>
-
-<Overlay isOpen={modal2Open}>
-  {/* Has its own backdrop on top */}
-</Overlay>
-```
-
-**Benefits:**
-- Shows depth through stacking
-- Each overlay can customize backdrop appearance
-- Matches user expectations from modern UI libraries
-
-### Nested Overlays Example
-
-```tsx
-import { OverlayProvider } from '@react-aria/overlays';
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Heading } from '@bento/heading';
-import { Text } from '@bento/text';
-import { Button } from '@bento/button';
-import { useState } from 'react';
-
-function App() {
-  return (
-    <OverlayProvider>
-      <MultiOverlayExample />
-    </OverlayProvider>
-  );
-}
-
-function MultiOverlayExample() {
-  const [settingsOpen, setSettingsOpen] = useState(false);
-  const [confirmOpen, setConfirmOpen] = useState(false);
-
-  return (
-    <Container>
-      <Button onPress={() => setSettingsOpen(true)}>
-        <Text>Open Settings</Text>
-      </Button>
-
-      {/* Settings Modal */}
-      <Overlay
-        isOpen={settingsOpen}
-        onOpenChange={setSettingsOpen}
-        aria-labelledby="settings-title"
-      >
-        <Container className="modal-content">
-          <Heading id="settings-title" level={2}>
-            Settings
-          </Heading>
-          <Text>Adjust your preferences</Text>
-
-          <Button onPress={() => setConfirmOpen(true)}>
-            <Text>Delete Account</Text>
-          </Button>
-
-          <Button onPress={() => setSettingsOpen(false)}>
-            <Text>Close</Text>
-          </Button>
-
-          {/* Confirmation Modal (nested) */}
-          <Overlay
-            isOpen={confirmOpen}
-            onOpenChange={setConfirmOpen}
-            isDismissable={false}
-            role="alertdialog"
-            aria-labelledby="confirm-title"
-          >
-            <Container className="modal-content">
-              <Heading id="confirm-title" level={2}>
-                Confirm Deletion
-              </Heading>
-              <Text>This action cannot be undone. Continue?</Text>
-
-              <Container className="modal-actions">
-                <Button onPress={() => setConfirmOpen(false)}>
-                  <Text>Cancel</Text>
-                </Button>
-                <Button onPress={() => {
-                  // Handle deletion
-                  setConfirmOpen(false);
-                  setSettingsOpen(false);
-                }}>
-                  <Text>Delete</Text>
-                </Button>
-              </Container>
-            </Container>
-          </Overlay>
-        </Container>
-      </Overlay>
-    </Container>
-  );
-}
-```
-
-**Behavior:**
-1. Opening confirmation modal: Settings modal backdrop visible, confirmation modal backdrop on top
-2. Focus: Automatically moves to confirmation modal
-3. Escape: Closes confirmation modal, focus returns to settings modal
-4. ARIA: Confirmation has `aria-modal="true"`, settings has `aria-hidden="true"`
-
-### Micro-Frontend Integration
-
-For micro-frontend architectures, wrap the shell in `OverlayProvider`:
-
-```tsx
-// Shell application
-import { OverlayProvider } from '@react-aria/overlays';
-
-function Shell() {
-  return (
-    <OverlayProvider>
-      <Header />
-      <MicroFrontend1 />
-      <MicroFrontend2 />
-      <Footer />
-    </OverlayProvider>
-  );
-}
-
-// Micro-frontend 1
-function MicroFrontend1() {
-  // Uses Bento Overlay - automatically coordinates with Shell's OverlayProvider
-  return (
-    <Overlay isOpen={isOpen} onOpenChange={setIsOpen}>
-      <Container>
-        <Text>MFE1 Modal Content</Text>
-      </Container>
-    </Overlay>
-  );
-}
-
-// Micro-frontend 2
-function MicroFrontend2() {
-  // Also uses Bento Overlay - stacks correctly with MFE1's modals
-  return (
-    <Overlay isOpen={isOpen} onOpenChange={setIsOpen}>
-      <Container>
-        <Text>MFE2 Modal Content</Text>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-**Result**: All micro-frontends' overlays:
-- Share the same stacking context
-- Coordinate z-index automatically
-- Manage focus correctly
-- Maintain proper ARIA attributes
-
-### Without OverlayProvider
-
-Overlay works standalone without `OverlayProvider`, but:
-
-**Limitations:**
-- No automatic z-index coordination between separate overlay instances
-- Manual z-index management required
-- Focus management less robust for multiple overlays
-- ARIA attributes not coordinated across overlays
-
-**When acceptable:**
-- Simple applications with only one overlay at a time
-- Controlled environments where z-index can be managed manually
-- Prototyping and development
-
-**Recommendation**: Always use `OverlayProvider` in production applications, especially:
-- Micro-frontend architectures
-- Applications with nested modals
-- Complex workflows with multiple overlays
-- Design systems supporting multiple consumers
-
-### Z-Index Management
-
-With `OverlayProvider`, z-index is managed automatically:
-
-**Base z-indexes by overlay type:**
-- Tooltips: 600
-- Popovers: 700
-- Dropdown Menus: 800
-- Modals/Dialogs: 1000
-- Toast Notifications: 1200
-
-**Stacking within type:**
-- First modal: 1000
-- Second modal (nested): 1010
-- Third modal (nested): 1020
-
-React ARIA increments z-index by 10 for each new overlay of the same type, ensuring proper stacking regardless of nesting depth.
-
-### Testing Multiple Overlays
-
-```tsx
-test('multiple modals stack correctly', async () => {
-  render(
-    <OverlayProvider>
-      <MultiOverlayExample />
-    </OverlayProvider>
-  );
-
-  // Open first modal
-  await user.click(screen.getByRole('button', { name: 'Open Settings' }));
-  const settingsDialog = screen.getByRole('dialog', { name: 'Settings' });
-  expect(settingsDialog).toHaveAttribute('aria-modal', 'true');
-
-  // Open second modal (nested)
-  await user.click(screen.getByRole('button', { name: 'Delete Account' }));
-  const confirmDialog = screen.getByRole('alertdialog', { name: 'Confirm Deletion' });
-
-  // Confirm modal is topmost
-  expect(confirmDialog).toHaveAttribute('aria-modal', 'true');
-  expect(settingsDialog).toHaveAttribute('aria-hidden', 'true');
-
-  // Close confirmation
-  await user.keyboard('{Escape}');
-  expect(confirmDialog).not.toBeInTheDocument();
-
-  // Settings modal is topmost again
-  expect(settingsDialog).toHaveAttribute('aria-modal', 'true');
-  expect(settingsDialog).not.toHaveAttribute('aria-hidden');
-});
-```
-
-### Best Practices
-
-1. **Always use OverlayProvider** in production apps
-2. **Test nested overlay scenarios** for complex UIs
-3. **Limit nesting depth** - typically max 2-3 levels for UX
-4. **Use appropriate roles** - `dialog` for modals, `alertdialog` for confirmations
-5. **Handle focus restoration** - let React ARIA manage it automatically
-6. **Customize backdrop opacity** - consider reducing opacity for nested overlays
-

-# Overlay Primitive PDR
-
-## Purpose
-
-The Overlay primitive provides a foundational building block for creating layered UI experiences where content appears above the main application view. It serves as a blank canvas that enables teams to build custom modal and drawer experiences with full flexibility, particularly optimized for mobile-first patterns.
-
-The Overlay primitive addresses several key scenarios:
-
-- Displaying content that requires immediate user attention or action
-- Creating focused interaction spaces that temporarily obscure the main content
-- Supporting mobile-first patterns like drawers, sheets, and action menus
-- Enabling rich compositional patterns through layering of UI elements
-
-This primitive will typically be consumed by:
-- Application developers building modal interfaces or drawers
-- Component authors creating specialized dialog components
-- Teams building loading indicators or notification systems
-- Any UI pattern requiring a visual layer between content and application
-
-### Unique Attributes
-
-The Overlay primitive differs from similar components in these key ways:
-
-- **Pure foundation**: Unlike most dialog components that combine multiple concerns, the Overlay provides only the backdrop and layering functionality, allowing maximum composition flexibility
-- **React Aria integration**: Built directly on React Aria's `useModalOverlay` and `useOverlay` hooks for best-in-class accessibility
-- **Slot-based composition**: Follows Bento's composition guidelines, passing state through slots for maximum customization
-- **Mobile-optimized**: Designed with mobile-first patterns in mind, supporting touch interactions and mobile gestures
-
-## Primitive Composition
-
-The Overlay primitive composes several standalone reusable primitives:
-
-### Core Primitives
-
-1. **@bento/portal** - Handles DOM rendering placement outside the normal hierarchy
-2. **@bento/backdrop** - Provides the semi-transparent backdrop layer behind overlay content
-3. **@bento/overlay-stack** - Manages multiple overlays with proper z-index and accessibility
-4. **@bento/focus-lock** - Contains keyboard focus within the overlay (existing primitive)
-5. **@bento/scroll-lock** - Prevents background scrolling (existing primitive)
-6. **@bento/dismiss-button** - Provides accessible dismiss functionality for screen readers
-7. **@bento/container** - Polymorphic rendering for overlay content
-
-### React Aria Integration
-
-The Overlay primitive builds directly upon React Aria's accessibility-focused hooks:
-
-- **useModalOverlay**: For backdrop and modal behavior (combines `useModal` + `useOverlay`)
-- **useOverlay**: For core overlay behavior (dismissal, escape key, outside clicks)
-- **useDialog**: For dialog-specific accessibility (when used in dialog contexts)
-
-## Implementation Patterns
-
-| Concept             | Implementation                                               |
-|---------------------|--------------------------------------------------------------|
-| React Aria          | useModalOverlay, useOverlay, useDialog                       |
-| Slots               | withSlots for component customization                        |
-| Render Props        | Support for className and style render props with meta object |
-| data-* Attributes   | data-open, data-modal, data-dismissable                     |
-| data-override       | Used when user customizes backdrop or content behavior       |
-| data-version        | Dev-only attribute for version tracking                      |
-| Composability       | Support for nested overlays, multiple overlays, context providers |
-
-## Internal Structure & Reuse Potential
-
-The Overlay component is designed as a minimal foundation that delegates to specialized primitives:

-
-  // Register with overlay stack when open
-  const overlayInfo = state.isOpen
-    ? stack.register(id, processedProps.overlayType || 'overlay')
-    : null;
-
-  useEffect(() => {
-    if (!state.isOpen) {
-      stack.unregister(id);
-    }

-
-  const dataAttributes = useDataAttributes({

-        priority: processedProps.priority || 2,
-        mfeId: processedProps.mfeId,
-        isOpen: state.isOpen,
-        controlled: processedProps.controlled
-      })
-    : null;
-
-  // Use orchestrated z-index if available, otherwise use stack z-index
-  const finalZIndex = layerOrchestration?.zIndex ?? overlayInfo?.zIndex ?? 1000;
-
-  return (
-    <Portal>
-      <Backdrop
-        {...underlayProps}

-              ...processedProps.style
-            }}
-            aria-modal={shouldBeModal ? 'true' : undefined}

-## React Aria or External Hook Integration
-
-### Why React Aria?
-
-After extensive research of different overlay implementations, React Aria stands out as the optimal foundation:
-
-1. **Accessibility excellence**: React Aria is built from the ground up with accessibility as the primary focus, ensuring WCAG compliance
-2. **Comprehensive feature set**: Provides complete solution for overlay functionality:
-   - Focus management with `useFocusScope` (wrapped in our FocusLock)
-   - Scroll locking with `usePreventScroll` (wrapped in our ScrollLock)
-   - Backdrop interaction with `useModalOverlay`
-   - Trigger management with `useOverlayTrigger`
-3. **Battle-tested**: Used extensively in Adobe's product ecosystem
-4. **Excellent mobile support**: Handles complex mobile edge cases including iOS Safari
-5. **Active maintenance**: Regular updates ensure compatibility with browser changes
-
-### Comparative Analysis
-
-We evaluated several libraries for overlay implementation:
-
-| Library | Strengths | Weaknesses | Focus Management | Multiple Overlay Support |
-|--------|-----------|------------|------------------|-------------------------|
-| React Aria | Exceptional a11y, robust focus management, strong mobile support | Less composable API | FocusScope component with complete trapping | OverlayContainer system |
-| Radix UI | Highly composable API, excellent animation support | Some mobile edge cases | Dialog-specific focus handling | Built-in dialog stack |
-| Ark UI | Flexible API, excellent composition | More complex API | FocusTrap component | Store-based dialog state |
-| Headless UI | Simplicity, good animation integration | Less flexible | Dialog-specific focus handling | Limited |
-| Material UI | Performance optimizations, comprehensive features | Less headless, more opinionated | Uses custom FocusTrap | ModalManager utility |
-
-React Aria provides the strongest foundation for accessibility and mobile support. We enhance it with Bento's composition model and slot-based customization.

-## Architecture & Features
-
-### Props Interface
-
-```tsx
-interface OverlayProps extends Slots {
-  /**
-   * Whether the overlay is open.
-   */
-  isOpen?: boolean;
-
-  /**
-   * Default open state (uncontrolled).
-   */
-  defaultOpen?: boolean;
-
-  /**
-   * Callback fired when open state changes.
-   */
-  onOpenChange?: (isOpen: boolean) => void;
-
-  /**
-   * Whether the overlay is modal (blocks interaction with background).
-   */
-  isModal?: boolean;
-
-  /**
-   * Whether the overlay can be dismissed.
-   */
-  isDismissable?: boolean;
-
-  /**
-   * Whether pressing Escape dismisses the overlay.
-   */
-  isKeyboardDismissDisabled?: boolean;
-
-  /**
-   * Whether clicking outside dismisses the overlay.
-   */
-  shouldCloseOnInteractOutside?: boolean | ((element: Element) => boolean);
-
-  /**
-   * Whether the overlay closes on blur.
-   */
-  shouldCloseOnBlur?: boolean;
-
-  /**
-   * Type of overlay for stacking purposes.
-   * Affects base z-index and stacking behavior.
-   * @default 'overlay'
-   */
-  overlayType?: 'tooltip' | 'popover' | 'dropdown' | 'overlay' | 'modal' | 'toast' | 'alert';
-
-  /**
-   * Content to render inside the overlay.
-   */
-  children?: React.ReactNode;

-### Slot Map
-
-| Slot Name    | Description                           | Required | Default Fallback |
-|--------------|---------------------------------------|----------|------------------|
-| `root`       | Top-level overlay container           | Yes      | Portal           |
-| `backdrop`   | Background layer behind content       | No       | Backdrop         |
-| `content`    | Container for overlay content         | Yes      | Container        |
-| `dismiss`    | Dismiss button (for screen readers)   | No       | DismissButton    |
-
-## Accessibility Highlights
-
-The Overlay primitive inherits React Aria's excellent accessibility features:
-
-- **ARIA roles**: Automatically applies `role="dialog"` or `role="alertdialog"` when appropriate
-- **Modal state**: Uses `aria-modal="true"` for modal overlays
-- **Focus management**: Implements proper focus trapping via FocusLock primitive
-- **Keyboard support**:
-  - Escape key to dismiss (configurable)
-  - Tab navigation contained within the overlay
-  - Return focus to trigger element on close
-- **Screen reader support**:
-  - Hides background content from screen readers when modal
-  - DismissButton provides accessible dismissal mechanism
-- **Proper handling of focus order** with multiple overlays
-
-For mobile accessibility:
-- Touch targets follow accessibility guidelines (minimum 44×44px)
-- Screen reader gestures properly supported
-- Visible focus indicators maintained for keyboard users
-
-## Internationalization, RTL, and Mobile Considerations
-
-The Overlay primitive is designed to work across different languages and layouts:
-
-- **RTL support**: The overlay positioning and animations work correctly in right-to-left layouts
-- **Mobile considerations**:
-  - Larger touch targets for mobile interactions
-  - Special handling for iOS Safari to prevent background content scrolling
-  - Support for mobile gestures (swipe to dismiss via composition)
-  - Adjustments for virtual keyboard appearance
-  - Responsive sizing and positioning
-
-- **Internationalization**: The component handles text expansion from different languages by using flexible layouts
-
-## Data Attributes and Slot Map
-
-### Expected `data-*` Attributes
-
-| Attribute             | Description                                   | Example Values         |
-|----------------------|-----------------------------------------------|------------------------|
-| `data-open`          | Whether the overlay is open                   | "true", "false"        |
-| `data-modal`         | Whether the overlay blocks interactions       | "true", "false"        |
-| `data-dismissable`   | Whether the overlay can be dismissed          | "true", "false"        |
-| `data-override`      | Indicates customized behavior                 | "style", "className"   |
-| `data-version`       | Component version (dev only)                  | "overlay@1.0"          |
-
-## Competitive Research
-
-### React Aria
-
-React Aria provides a robust set of hooks for building accessible overlays:
-
-- **useOverlay**: Manages ARIA attributes and keyboard interactions
-- **useModalOverlay**: Adds modal-specific behaviors like backdrop interaction
-- **useFocusScope**: Handles focus containment
-- **usePreventScroll**: Manages scroll locking with excellent cross-browser support
-- **useOverlayPosition**: Supports positioning relative to trigger elements
-- **useOverlayTrigger**: Connects trigger elements to overlays
-
-React Aria excels at accessibility but has a more imperative API that requires additional work to fit into Bento's composable component model.
-
-### Park UI / Ark UI
-
-Park UI (built on Ark UI) offers a highly composable dialog component:
-
-```jsx
-// Ark UI approach
-<Dialog.Root>
-  <Dialog.Trigger />
-  <Dialog.Portal>
-    <Dialog.Backdrop />
-    <Dialog.Content>
-      <Dialog.Title />
-      <Dialog.Close />
-    </Dialog.Content>
-  </Dialog.Portal>
-</Dialog.Root>
-```
-
-Strengths:
-- Excellent composition model
-- Good animation support via data attributes
-- Solid accessibility
-
-Weaknesses:
-- Some mobile edge cases
-- Different composition model (asChild pattern)
-
-### Radix UI
-
-Radix UI offers a highly composable dialog component:
-
-```jsx
-// Radix UI approach
-<Dialog.Root>
-  <Dialog.Trigger />
-  <Dialog.Portal>
-    <Dialog.Overlay />
-    <Dialog.Content>
-      <Dialog.Title />
-      <Dialog.Description />
-      <Dialog.Close />
-    </Dialog.Content>
-  </Dialog.Portal>
-</Dialog.Root>
-```
-
-Strengths:
-- Excellent composition model
-- Good animation support via data attributes
-- Solid accessibility
-
-Weaknesses:
-- Some mobile edge cases
-- Occasional focus management issues in complex scenarios

-          </Button>
-          <Button onPress={() => setConfirmOpen(false)}>Cancel</Button>
-        </Container>
-      </Overlay>
-    </OverlayStack.Provider>
-  );
-}
-```
-
-### Micro-frontend coordination (Layer Orchestrator)
-
-**Zero configuration needed!** Components handle z-index coordination automatically:
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { LAYER_PRIORITY } from '@bento/layer-orchestrator';
-import { useState } from 'react';
-
-// Example: Cookie Consent MFE (Bento v1)
-function CookieConsentMFE() {
-  const [isOpen, setIsOpen] = useState(true);
-
-  // Just use the component - z-index coordination is automatic!
-  return (
-    <Overlay
-      isOpen={isOpen}
-      onOpenChange={setIsOpen}
-      isModal
-      mfeId="legal-mfe"
-      type="modal"
-      priority={LAYER_PRIORITY.HIGH} // High priority - interrupts tours
-      controlled // Only render when topmost
-    >
-      <Container slot="content">
-        <Text as="h2">Cookie Consent</Text>
-        <Text>We need your consent to use cookies.</Text>
-        <Button onPress={() => setIsOpen(false)}>Accept</Button>
-      </Container>
-    </Overlay>
-  );
-}
-
-// Example: Product Tour MFE (Bento v2)
-function ProductTourMFE() {
-  const [currentStep, setCurrentStep] = useState(0);
-  const steps = [/* ... */];
-
-  // Just use the component - queuing and z-index are automatic!
-  return (
-    <Overlay
-      isOpen={currentStep < steps.length}
-      overlayType="tour"
-      mfeId="product-mfe"
-      priority={LAYER_PRIORITY.LOW} // Low priority - can be interrupted
-      controlled // Only render when topmost (queued otherwise)
-    >
-      <Container slot="content">
-        <Text>{steps[currentStep].content}</Text>
-        <Button onPress={() => setCurrentStep(currentStep + 1)}>Next</Button>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-**Key points:**
-- **No manual z-index**: Components automatically set CSS variables and handle calc()
-- **No useLayerOrchestration hook**: Components use it internally
-- Each MFE provides unique `mfeId` for identification
-- `priority` determines which overlay appears above others
-- `controlled` prop handles queuing automatically
-- All MFEs independently calculate z-index from synced state
-- No host application or leader required
-
-See `layer-orchestrator.mdx` for detailed implementation and architecture.
-
-## Multiple Overlays and Stacking
-
-### Single Bundle: OverlayStack
-
-When multiple overlays are open simultaneously **within the same JavaScript bundle**, use `OverlayStack.Provider` to manage proper stacking:
-
-1. **Visual stacking**: Higher z-index for overlays opened later
-2. **Accessibility**: Only topmost modal has `aria-modal="true"`
-3. **Focus management**: Focus transfers correctly when overlays open/close
-4. **Type-based layering**: Different overlay types have different base z-indexes
-
-**Use OverlayStack when:**
-- All overlays come from the same JavaScript bundle
-- Shared React context is available
-- No micro-frontend architecture
-
-See `overlay-stack.mdx` for detailed stacking implementation.
-
-### Micro-Frontends: Layer Orchestrator
-
-When overlays come from **different JavaScript bundles (micro-frontends)**, use the **Layer Orchestrator** for distributed, peer-to-peer coordination **without requiring a host application**:
-
-1. **Distributed coordination**: Each MFE maintains its own state and syncs via events (no single leader)
-2. **Event-driven synchronization**: All instances broadcast state changes; all instances update independently
-3. **Version compatibility**: Different MFEs can use different Bento versions (v1, v2, v3) via protocol versioning
-4. **Cross-bundle coordination**: Works via DOM/CustomEvents and optional DOM/sessionStorage backup
-5. **Priority-based control**: Higher priority layers automatically appear above lower priority layers
-6. **Queue system**: Experiences can be queued when higher priority experiences are active
-7. **Universal orchestration**: Works for overlays, toasts, product tours, any layered UI
-8. **No single point of failure**: If one MFE fails, others continue coordinating independently
-
-**Use Layer Orchestrator when:**
-- Multiple micro-frontends launch competing overlay experiences
-- Different JavaScript bundles cannot share React context
-- No host application available to coordinate
-- MFEs may be using different Bento versions (v1, v2, v3)
-- Need to coordinate cookie consent, product tours, live chat, modals from different MFEs
-- Need priority-based control (e.g., cookie consent interrupts product tour)
-- Insert order/z-index alone don't work (MFEs load in unpredictable order)
-
-**Example scenarios:**
-- Product tour MFE (Bento v2) starts overlay, Legal MFE (Bento v1) shows cookie consent (high priority) → Cookie consent appears above tour via distributed z-index calculation
-- Live chat MFE (Bento v3) active, another MFE (Bento v1) needs critical modal → Modal appears above chat via event-based coordination
-- Two MFEs (different versions) want to show growls → Only one visible at a time, others queued via distributed queue
-
-**Key difference from OverlayStack**: OverlayStack requires shared React context (single bundle). Layer Orchestrator uses distributed event-driven synchronization across bundles and versions without requiring a leader or host.
-
-See `layer-orchestrator.mdx` for detailed peer-to-peer orchestration implementation.
-
-### Stacking Behavior (Both Systems)
-
-- **Registration**: Overlays register when they open
-- **Z-index calculation**: Based on overlay type and existing stack/orchestrator state
-- **Topmost determination**: Only topmost overlay is fully accessible
-- **Focus transfer**: When overlay closes, focus returns to previous overlay or trigger
-
-### UX Considerations
-
-While multiple overlays are technically supported, consider UX:
-
-- **Confirmation dialogs**: Appropriate use case
-- **Nested workflows**: Can work but consider alternatives
-- **Too many layers**: Can confuse users; prefer alternatives like:
-  - Inline expansion
-  - Side panels
-  - Step-by-step within single overlay
-  - Navigation to dedicated page
-
-## Decision Checklist
-
-When building with the Overlay primitive:
-
-- [ ] Is this overlay modal or non-modal?
-- [ ] Does it need a backdrop?
-- [ ] Should it close on outside click?
-- [ ] Should it close on Escape key?
-- [ ] Does it need focus trapping? (usually yes for modals)
-- [ ] Does it need scroll locking? (usually yes for modals)
-- [ ] How should it be positioned? (centered, drawer, etc.)
-- [ ] What content needs to be in the overlay?
-- [ ] Are there accessibility requirements specific to this use case?
-- [ ] Will this overlay appear with others? (requires OverlayStack.Provider)
-- [ ] What overlay type is this? (modal, popover, tooltip, etc.)

-# Overlay Primitive PDR
-
-## Purpose
-
-The Overlay primitive serves as a foundational building block for creating layered UI experiences where content appears above the main application view. It provides the core backdrop functionality that supports various overlay-based patterns such as modals, dialogs, drawers, and loading indicators.
-
-The Overlay primitive addresses several key scenarios:
-
-- Displaying content that requires immediate user attention or action
-- Creating focused interaction spaces that temporarily obscure the main content
-- Supporting mobile-first patterns like drawers, sheets, and action menus
-- Enabling rich compositional patterns through layering of UI elements
-
-This primitive will typically be consumed by:
-- Application developers building modal interfaces or drawers
-- Component authors creating specialized dialog components
-- Teams building loading indicators or notification systems
-- Any UI pattern requiring a visual layer between content and application
-
-### Unique Attributes
-
-The Overlay primitive differs from similar components in these key ways:
-
-- **Pure foundation**: Unlike most dialog components that combine multiple concerns, the Overlay provides only the backdrop and layering functionality, allowing maximum composition flexibility
-- **Blank canvas approach**: Teams have complete control over content structure and styling
-- **Composable primitives**: Built from smaller, reusable primitives (Portal, Backdrop, DismissableLayer) that can be used independently
-- **React Aria foundation**: Leverages React Aria's battle-tested accessibility hooks
-- **Slot-based composition**: Follows Bento's slot system for maximum customization
-
-## Primitive Composition
-
-The Overlay primitive composes several standalone reusable primitives, maximizing code sharing across the Bento ecosystem:
-
-### Core Primitive Packages
-
-Each primitive will be its own package following Bento's architecture:
-
-- **@bento/portal**: Handles DOM rendering placement outside the normal hierarchy
-- **@bento/backdrop**: Visual backdrop that sits behind content with click handling
-- **@bento/dismissable-layer**: Handles dismissal interactions (outside clicks, Escape key)
-- **@bento/focus-lock**: Contains keyboard focus within a boundary (already exists via focus-lock-primitive.mdx)
-- **@bento/scroll-lock**: Prevents background scrolling (already exists via scrolllock-pdr.mdx)
-
-### Overlay Component Structure
-
-The Overlay component uses slot-based composition where children are provided with `slot` attributes:
-- `trigger` slot: Element that opens/closes the overlay (uses React Aria's useOverlayTrigger)
-- `backdrop` slot: Visual backdrop behind content (uses @bento/backdrop, conditionally rendered for modal overlays)
-- `content` slot: Main overlay content with proper layering, focus handling, and dismissal (uses Portal, DismissableLayer, FocusLock)
-
-### React Aria Integration
-
-All primitives build directly upon React Aria's accessibility-focused hooks:
-
-- **useOverlay**: For core overlay behavior (dismissal, escape key handling)
-- **useModalOverlay**: For backdrop and modal behavior (hiding content from screen readers)
-- **useModal**: For hiding content outside overlay container from assistive technologies
-- **useOverlayTrigger**: For trigger elements to open/close overlays
-- **usePreventScroll**: For scroll locking (wrapped in @bento/scroll-lock)
-
-## Implementation Patterns
-
-| Concept             | Implementation                                               |
-|---------------------|--------------------------------------------------------------|
-| React Aria          | useOverlay, useModalOverlay, useModal, useOverlayTrigger      |
-| Slots               | withSlots for component customization                        |
-| Render Props        | Support for className and style render props with state object |
-| data-* Attributes   | data-open, data-modal, data-dismissable, data-animated       |
-| data-override       | Used when user customizes backdrop or content behavior       |
-| data-version        | Dev-only attribute for version tracking                      |
-| Composability       | Support for nested content, multiple overlays, context providers |
-
-## Internal Structure & Reuse Potential
-
-Each primitive is designed for maximum reusability across the Bento ecosystem:

-- Any component that should prevent background scrolling
-
-## React Aria Integration
-
-### Why React Aria?
-
-After extensive research of different overlay implementations, React Aria stands out as the optimal foundation for several reasons:
-
-1. **Accessibility excellence**: React Aria is built from the ground up with accessibility as the primary focus, ensuring WCAG compliance.
-
-2. **Comprehensive feature set**: React Aria provides a complete solution for overlay functionality:
-   - Focus management with FocusScope
-   - Scroll locking with usePreventScroll
-   - Backdrop interaction with useModalOverlay
-   - Trigger management with useOverlayTrigger
-   - Core overlay behavior with useOverlay
-
-3. **Battle-tested in production**: Used extensively in Adobe's product ecosystem, ensuring robust performance in real-world applications.
-
-4. **Excellent mobile support**: Handles complex mobile edge cases that other libraries miss, including iOS Safari scroll handling.
-
-5. **Active maintenance**: Regular updates and community support ensure the library stays current with browser changes and accessibility standards.
-
-### React Aria Hooks Usage
-
-- **useOverlay**: Core overlay behavior including Escape key handling, outside click detection, and proper ARIA attributes. Returns `overlayProps` to spread on overlay content.
-
-- **useModalOverlay**: Modal-specific behavior including backdrop props (`underlayProps`), scroll locking, and hiding content outside modal from screen readers. Returns both `overlayProps` and `underlayProps`.
-
-- **useModal**: Hides content outside the current OverlayContainer from screen readers, ensuring only the top-most modal is accessible. Returns `modalProps` to spread on overlay container.
-
-- **useOverlayTrigger**: Connects trigger elements to overlays, managing state and keyboard interactions. Returns `triggerProps` and `overlayProps`.
-
-- **usePreventScroll**: Prevents scrolling on the document body (already wrapped in @bento/scroll-lock).
-
-### Comparative Analysis
-
-We evaluated several libraries for overlay implementation:
-
-| Library | Strengths | Weaknesses | Focus Management | Multiple Overlay Support |
-|---------|-----------|------------|------------------|--------------------------|
-| React Aria | Exceptional a11y, robust focus management, strong mobile support | Less composable API | FocusScope component with complete trapping | OverlayContainer system |
-| Radix UI | Highly composable API, excellent animation support | Some mobile edge cases | Dialog-specific focus handling | Built-in dialog stack |
-| Ark UI | Flexible API, excellent composition | More complex API | FocusTrap component | Store-based dialog state |
-| Headless UI | Simplicity, good animation integration | Less flexible | Dialog-specific focus handling | Limited |
-| Material UI | Performance optimizations, comprehensive features | Less headless, more opinionated | Uses custom FocusTrap | ModalManager utility |
-
-React Aria provides the strongest foundation for accessibility and mobile support, which are top priorities. We'll enhance it with Bento's composition model and slot system.
-
-## Overlay Stack Management
-
-A critical requirement is handling multiple active overlays simultaneously (overlay stacks). When multiple modals, dialogs, or overlays are open at the same time, the system must manage visual stacking, focus, accessibility, and user interactions correctly.
-
-### Stacking Challenges
-
-When multiple overlays are active, four key aspects must be coordinated:
-
-1. **Visual stacking (z-index)**: Which overlay appears on top visually
-2. **Focus management**: Which overlay receives keyboard focus and traps focus
-3. **Accessibility (ARIA)**: Proper aria-modal and aria-hidden attributes for screen readers
-4. **Interaction boundaries**: How clicks, keyboard events, and dismissals propagate through layers
-
-### UX Patterns for Multiple Overlays
-
-Different UX patterns are possible with overlay stacks:
-
-#### Pattern 1: Stacked Modals (Sequential Dismissal)
-- Each new modal appears above previous ones
-- Only the topmost modal is interactive
-- Closing the topmost modal reveals the one below
-- User must dismiss modals in reverse order (LIFO - Last In, First Out)
-- **Example**: Opening a settings modal, then opening a "Are you sure?" confirmation modal from within it
-
-#### Pattern 2: Independent Overlays
-- Multiple overlays can coexist independently
-- Each overlay manages its own focus and interactions
-- Overlays don't block each other
-- **Example**: A tooltip and a dropdown menu open simultaneously
-
-#### Pattern 3: Replacement Pattern
-- Opening a new overlay automatically closes previous ones
-- Only one overlay visible at a time
-- **Example**: Opening a different drawer automatically closes the currently open drawer
-
-### Single-Bundle Stack Management (React Aria)
-
-For single-bundle applications, React Aria provides `OverlayContainer` which handles overlay stacks automatically:
-
-```tsx
-import { OverlayContainer } from '@react-aria/overlays';
-
-// Wrap your app with OverlayContainer
-<OverlayContainer>
-  <App />
-</OverlayContainer>
-```
-
-**How it works:**
-- Uses React Context to track overlay hierarchy (requires single React tree)
-- Automatically manages `aria-hidden` on inactive overlays
-- Ensures only topmost modal has `aria-modal="true"`
-- Coordinates focus management across layers
-- Handles proper event propagation
-
-**Key features:**
-- Zero configuration needed - works automatically when overlays are portaled
-- Tracks overlay registration order
-- Manages z-index automatically (via React Aria's internal system)
-- Properly hides inactive overlays from screen readers
-
-**Limitations:**
-- **Single bundle only**: Requires shared React Context (doesn't work across micro frontends)
-- **No priority system**: Only insertion order matters
-- **No ownership model**: Cannot track which part of app owns each layer
-
-### Multi-Bundle Stack Orchestration
-
-For micro-frontend architectures with multiple independent JavaScript bundles, React Aria's OverlayContainer cannot work because bundles cannot share React Context. We provide `@bento/stack-orchestration` for cross-bundle coordination.
-
-**See [stack-orchestration-primitive.mdx](./stack-orchestration-primitive.mdx) for complete details.**
-
-**How it works:**
-- Uses DOM and Custom Events for cross-bundle communication (no shared React state)
-- Maintains global registry via window object accessible to all bundles
-- Supports priority-based stacking (not just insertion order)
-- Tracks ownership (which MFE owns each layer)
-- Works for overlays, toasts, growls, product tours, and any layered UI
-
-**Key features:**
-- **Cross-bundle coordination**: Works across independent JavaScript bundles
-- **Priority system**: Higher priority layers appear on top
-- **Ownership tracking**: Know which MFE owns each layer
-- **Universal applicability**: Works for any layered UI, not just overlays
-- **Host-controlled**: Host application installs orchestrator, MFEs register with it
-
-### Implementation with Bento Overlay
-
-#### Single-Bundle Scenario (React Aria)
-
-Our Overlay primitive integrates with React Aria's OverlayContainer for single-bundle applications:
-
-```tsx
-import { OverlayContainer } from '@react-aria/overlays';
-import { Overlay } from '@bento/overlay';
-
-function App() {
-  return (
-    <OverlayContainer>
-      <PageContent />
-
-      {/* First overlay */}
-      <Overlay isOpen={firstOpen} onOpenChange={setFirstOpen} modal>
-        <Container slot="content">
-          <Text>First Modal</Text>
-          <Button onClick={() => setSecondOpen(true)}>Open Second</Button>
-        </Container>
-      </Overlay>
-
-      {/* Second overlay (stacked above first) */}
-      <Overlay isOpen={secondOpen} onOpenChange={setSecondOpen} modal>
-        <Container slot="content">
-          <Text>Second Modal (on top)</Text>
-          <Button onClick={() => setSecondOpen(false)}>Close</Button>
-        </Container>
-      </Overlay>
-    </OverlayContainer>
-  );
-}
-```
-
-#### Multi-Bundle Scenario (Stack Orchestration)
-
-For micro-frontend architectures, use stack orchestration:
-
-```tsx
-// No host setup needed - registry created automatically
-// Inside any MFE
-import { useStackLayer } from '@bento/stack-orchestration';
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-
-function MFEModal() {
-  const [isOpen, setIsOpen] = useState(false);
-  const overlayRef = useRef<HTMLDivElement>(null);
-  const { zIndex, isTopmost } = useStackLayer({
-    priority: 1000, // Legal consent = critical priority
-    type: 'modal',
-    mfeId: 'legal-mfe',
-    isOpen,
-    elementRef: overlayRef
-  });
-
-  return (
-    <Overlay isOpen={isOpen} onOpenChange={setIsOpen} modal>
-      <Container
-        slot="content"
-        ref={overlayRef}
-        style={{ zIndex }}
-        data-stack-topmost={isTopmost}
-      >
-        <Text>Legal consent modal</Text>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-**How it works:**
-- First MFE to register initializes global registry object (`window.__bentoStackRegistry`)
-- All MFEs read/write to same global object (peer-to-peer, no DOM mutation)
-- Each MFE calculates z-index independently from global state
-- Works across different Bento versions (v1, v2, v3)
-- No host application or central orchestrator required
-- **Zero performance impact**: Global object mutations don't trigger re-renders or style recalculation
-
-### Stack Behavior Details
-
-#### Visual Stacking (Z-Index)
-
-React Aria's OverlayContainer automatically manages z-index values:
-- Base z-index for overlays (typically 1000+)
-- Each new overlay gets an incrementally higher z-index
-- Ensures proper visual hierarchy
-- Our Overlay primitive respects this system
-
-#### Nested Layers: Dropdowns Inside Modals
-
-**Simple Solution: Use CSS Variables + Calc**
-
-When a dropdown is rendered inside a modal, use CSS custom properties to coordinate z-index values:
-
-```tsx
-function ModalWithDropdown() {
-  const modalRef = useRef<HTMLDivElement>(null);
-  const { zIndex: modalZIndex } = useStackLayer({
-    type: 'modal',
-    mfeId: 'my-mfe',
-    isOpen: modalOpen,
-    elementRef: modalRef,
-    priority: 100
-  });
-
-  return (
-    <Overlay isOpen={modalOpen}>
-      <Container
-        slot="content"
-        ref={modalRef}
-        style={{
-          zIndex: modalZIndex,
-          '--layer-z-index': modalZIndex // CSS variable for nested layers
-        }}
-      >
-        <Select>
-          {/* Dropdown uses calc() relative to modal's z-index */}
-          <div style={{ zIndex: 'calc(var(--layer-z-index) + 10)' }}>
-            Dropdown content
-          </div>
-        </Select>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-**How it works:**
-1. Modal registers with stack orchestration → gets z-index (e.g., 5000)
-2. Stack orchestration sets CSS variable `--layer-z-index: 5000` on modal element
-3. Dropdown uses `calc(var(--layer-z-index) + 10)` → automatically gets z-index: 5010
-4. CSS handles calculation, no JavaScript needed
-5. No need to register dropdown separately or track parent-child relationships
-
-**Benefits:**
-- **Simple**: Standard CSS features (variables + calc)
-- **Performant**: CSS handles calculations
-- **Flexible**: Easy to adjust offsets
-- **No complexity**: No parentId tracking or context lookups
-
-**When to Portal:**
-- Portal is still needed for the modal itself (to escape page content)
-- Portal nested layers only if parent creates problematic stacking context (transform, opacity < 1, etc.)
-- Otherwise, CSS variables handle z-index coordination automatically
-
-**Custom z-index**: Teams can override via slots if needed:
-```tsx
-<Overlay
-  isOpen={isOpen}
-  onOpenChange={setIsOpen}
-  slots={{
-    content: {
-      style: { zIndex: 9999 }
-    }
-  }}
->
-  <Container slot="content">Custom z-index</Container>
-</Overlay>
-```
-
-#### Focus Management
-
-Focus behavior in stacks:
-1. **Opening new overlay**: Focus moves to new overlay (via FocusLock)
-2. **Closing top overlay**: Focus returns to previous overlay or trigger
-3. **Focus trapping**: Only topmost overlay traps focus
-4. **Tab navigation**: Contained within active overlay
-
-React Aria's `useModal` hook ensures:
-- Lower overlays don't intercept focus
-- Focus is properly restored when overlays close
-- Screen reader navigation works correctly
-
-#### ARIA Attributes in Stacks
-
-React Aria's `useModal` hook automatically manages:
-- **Topmost modal**: Gets `aria-modal="true"`
-- **Lower modals**: Get `aria-hidden="true"` (hidden from screen readers)
-- **Non-modal overlays**: Don't affect other overlays' ARIA state
-
-This ensures:
-- Screen readers only announce the active overlay
-- Keyboard users can't interact with hidden overlays
-- Proper accessibility tree structure
-
-### Stack Configuration Options
-
-The Overlay primitive supports different stack management strategies:
-
-#### Single-Bundle (React Aria)
-
-React Aria's OverlayContainer handles everything automatically - no configuration needed.
-
-#### Multi-Bundle (Stack Orchestration)
-
-Configure via `useStackLayer` hook:
-
-```tsx
-interface UseStackLayerOptions {
-  /**
-   * Priority - higher priority overlays appear on top.
-   * Recommended priorities:
-   * - CRITICAL: 1000 (legal consent, security)
-   * - HIGH: 500 (important modals)
-   * - MEDIUM: 100 (standard modals)
-   * - LOW: 50 (product tours)
-   * - NOTIFICATION: 10 (toasts)
-   * @default 0
-   */
-  priority?: number;
-
-  /**
-   * Type of layer - affects base z-index calculation.
-   */
-  type: 'modal' | 'toast' | 'tooltip' | 'overlay' | 'product-tour';
-
-  /**
-   * MFE identifier - tracks which micro frontend owns this layer.
-   */
-  ownerId: string;
-
-  /**
-   * Element ref - DOM element to apply z-index to.
-   */
-  elementRef?: React.RefObject<HTMLElement>;
-}
-```
-
-### Integration Requirements
-
-#### Single-Bundle Applications
-
-1. **Wrap app with OverlayContainer**:
-```tsx
-import { OverlayContainer } from '@react-aria/overlays';
-
-function App() {
-  return (
-    <OverlayContainer>
-      {/* All overlays must be inside OverlayContainer */}
-      <YourApp />
-    </OverlayContainer>
-  );
-}
-```
-
-2. **Use Portal** (handled automatically by Overlay):
-   - All overlays must be portaled to same container (default: document.body)
-   - React Aria tracks portaled overlays for stack management
-
-3. **Modal prop coordination**:
-   - Only modal overlays participate in stack blocking behavior
-   - Non-modal overlays (popovers, tooltips) don't block interactions
-
-#### Micro-Frontend Applications
-
-1. **No setup required** - Registry is created automatically when first MFE registers a layer.
-
-2. **Each MFE uses useStackLayer hook independently**:
-```tsx
-import { useStackLayer } from '@bento/stack-orchestration';
-
-function MFEModal() {
-  const [isOpen, setIsOpen] = useState(false);
-  const ref = useRef<HTMLDivElement>(null);
-  const { zIndex, isTopmost } = useStackLayer({
-    priority: 1000,
-    type: 'modal',
-    mfeId: 'my-mfe-id',
-    isOpen,
-    elementRef: ref
-  });
-
-  // Apply zIndex to overlay element
-}
-```
-
-3. **Portal coordination**:
-   - All overlays portaled to same container (default: document.body)
-   - Stack orchestration manages z-index across all portaled layers through global registry (`window.__bentoStackRegistry`)
-   - Works even when MFEs are in different React trees
-
-**Note**: Stack orchestration is **optional but recommended** for micro-frontend scenarios. Without it, overlays from different MFEs may conflict and stack randomly. With it, coordination happens automatically through peer-to-peer global object registry with zero performance overhead.
-
-### Micro-Frontend Scenarios Requiring Orchestration
-
-The following scenarios break without stack orchestration and demonstrate why coordination is essential:
-
-#### Scenario 1: Product Tour vs Legal Consent
-
-**Problem**:
-- Product Tour MFE wants to start onboarding with overlay and popovers
-- Legal Consent MFE must get cookie consent from user
-- Both try to show simultaneously
-
-**Without Orchestration**:
-- Layers stack randomly or conflict
-- User sees confusing mixed UI
-- Legal consent might be hidden
-
-**With Orchestration**:
-```tsx
-// Legal Consent MFE (high priority)
-const { zIndex } = useStackLayer({
-  priority: 1000, // CRITICAL
-  type: 'modal',
-  mfeId: 'legal-mfe',
-  isOpen: true,
-  elementRef: legalRef
-});
-
-// Product Tour MFE (low priority)
-const { zIndex } = useStackLayer({
-  priority: 50, // LOW
-  type: 'product-tour',
-  mfeId: 'product-tour-mfe',
-  isOpen: true,
-  elementRef: tourRef
-});
-
-// Result: Legal consent appears above product tour via global registry coordination
-```
-
-#### Scenario 2: Live Chat vs Host Modal
-
-**Problem**:
-- Live Chat MFE shows chat widget overlay
-- Host application needs to show critical modal
-- Which should be on top?
-
-**Without Orchestration**:
-- Chat might block modal or vice versa
-- No way to coordinate priority
-
-**With Orchestration**:
-```tsx
-// Live Chat MFE (medium priority)
-const { zIndex } = useStackLayer({
-  priority: 100, // MEDIUM
-  type: 'overlay',
-  mfeId: 'chat-mfe',
-  isOpen: true,
-  elementRef: chatRef
-});
-
-// Critical Modal MFE (high priority)
-const { zIndex } = useStackLayer({
-  priority: 500, // HIGH
-  type: 'modal',
-  mfeId: 'security-mfe',
-  isOpen: true,
-  elementRef: modalRef
-});
-
-// Result: Critical modal appears above chat when both are open via global registry coordination
-```
-
-#### Scenario 3: Multiple Toast/Growl Notifications
-
-**Problem**:
-- Checkout MFE wants to show success toast
-- Inventory MFE wants to show error toast
-- Both try to display simultaneously
-
-**Without Orchestration**:
-- Toasts stack randomly on top of each other
-- User can't see both messages
-- No coordination between MFEs
-
-**With Orchestration**:
-```tsx
-// Both MFEs use same type with notification priority
-const { zIndex, isTopmost } = useStackLayer({
-  priority: 10, // NOTIFICATION
-  type: 'toast',
-  mfeId: 'checkout-mfe', // or 'inventory-mfe'
-  isOpen: true,
-  elementRef: toastRef
-});
-
-// Global object coordination ensures:
-// - Toasts don't overlap randomly
-// - They stack in order with proper spacing
-// - Only topmost toast receives focus (if applicable)
-```
-
-#### Scenario 4: Multiple Product Tours
-
-**Problem**:
-- Two different MFEs both try to start product tours
-- Both have overlays and popovers
-- User experience becomes confusing
-
-**Without Orchestration**:
-- Tours conflict and overlap
-- User sees multiple competing experiences
-- No way to determine which should take precedence
-
-**With Orchestration**:
-```tsx
-// Both register with different priorities
-const { zIndex } = useStackLayer({
-  priority: 75, // Higher priority tour
-  type: 'product-tour',
-  ownerId: 'main-tour-mfe',
-  elementRef: tourRef
-});
-
-// Lower priority tour waits or defers
-// Host can implement policies (e.g., only one tour at a time)
-```
-
-### Stack UX Best Practices
-
-Based on research and accessibility guidelines:
-
-1. **Limit stack depth**: Avoid more than 2-3 stacked modals to prevent user confusion
-2. **Visual hierarchy**: Make it clear which overlay is active (higher z-index, distinct styling)
-3. **Dismissal order**: Users expect to dismiss in reverse order (most recent first)
-4. **Escape key**: Should close only the topmost overlay
-5. **Backdrop clicks**: Should close only the topmost modal
-6. **Focus indication**: Clear visual indication of which overlay has focus
-7. **Priority guidelines**: Establish clear priority levels across MFEs (e.g., legal > critical modals > tours > notifications)
-8. **Ownership cleanup**: MFEs should clean up all their layers on unmount to prevent orphaned overlays
-
-### Code Examples: Multiple Overlays
-
-#### Stacked Modals
-
-```tsx
-import { OverlayContainer } from '@react-aria/overlays';
-import { Overlay } from '@bento/overlay';
-import { Button } from '@bento/button';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-
-function StackedModals() {
-  const [firstOpen, setFirstOpen] = useState(false);
-  const [secondOpen, setSecondOpen] = useState(false);
-
-  return (
-    <OverlayContainer>
-      <Button onClick={() => setFirstOpen(true)}>Open First Modal</Button>
-
-      {/* First modal */}
-      <Overlay isOpen={firstOpen} onOpenChange={setFirstOpen} modal>
-        <Container slot="content">
-          <Text>First Modal</Text>
-          <Button onClick={() => setSecondOpen(true)}>Open Second Modal</Button>
-          <Button onClick={() => setFirstOpen(false)}>Close First</Button>
-        </Container>
-      </Overlay>
-
-      {/* Second modal (stacks above first) */}
-      <Overlay isOpen={secondOpen} onOpenChange={setSecondOpen} modal>
-        <Container slot="content">
-          <Text>Second Modal (on top)</Text>
-          <Text>Press Escape to close this, revealing first modal</Text>
-          <Button onClick={() => setSecondOpen(false)}>Close Second</Button>
-        </Container>
-      </Overlay>
-    </OverlayContainer>
-  );
-}
-```
-
-#### Independent Overlays (Non-blocking)
-
-```tsx
-import { OverlayContainer } from '@react-aria/overlays';
-import { Overlay } from '@bento/overlay';
-
-function IndependentOverlays() {
-  const [tooltipOpen, setTooltipOpen] = useState(false);
-  const [popoverOpen, setPopoverOpen] = useState(false);
-
-  return (
-    <OverlayContainer>
-      {/* Non-modal overlays don't block each other */}
-      <Overlay isOpen={tooltipOpen} onOpenChange={setTooltipOpen} modal={false}>
-        <Container slot="content">Tooltip content</Container>
-      </Overlay>
-
-      <Overlay isOpen={popoverOpen} onOpenChange={setPopoverOpen} modal={false}>
-        <Container slot="content">Popover content</Container>
-      </Overlay>
-    </OverlayContainer>
-  );
-}
-```
-
-#### Conditional Stack Management
-
-```tsx
-import { OverlayContainer } from '@react-aria/overlays';
-import { Overlay } from '@bento/overlay';
-
-function ConditionalStack() {
-  const [drawerOpen, setDrawerOpen] = useState(false);
-  const [modalOpen, setModalOpen] = useState(false);
-
-  // Modal should close drawer when opened
-  useEffect(() => {
-    if (modalOpen && drawerOpen) {
-      setDrawerOpen(false);
-    }
-  }, [modalOpen, drawerOpen]);
-
-  return (
-    <OverlayContainer>
-      <Overlay isOpen={drawerOpen} onOpenChange={setDrawerOpen} modal={false}>
-        <Container slot="content">Drawer</Container>
-      </Overlay>
-
-      <Overlay isOpen={modalOpen} onOpenChange={setModalOpen} modal>
-        <Container slot="content">Modal (closes drawer)</Container>
-      </Overlay>
-    </OverlayContainer>
-  );
-}
-```
-
-## Focus Management
-
-Focus management is consistently the most critical and complex aspect of overlay implementations. Based on our research, we identified these key requirements:
-
-1. **Focus trapping**: Prevents tabbing outside the overlay while it's open
-2. **Initial focus control**: Allows specifying which element receives focus when opened
-3. **Return focus**: Returns focus to the trigger element when closed
-4. **Focus stack**: Manages focus between multiple overlays
-
-React Aria's FocusScope is the most robust solution we evaluated, handling edge cases like:
-- Browser extensions that inject focusable elements
-- Shadow DOM boundaries
-- Dynamic content changes
-- Screen reader navigation
-
-Our @bento/focus-lock primitive (already exists) preserves these capabilities while adapting to Bento's patterns.
-
-## Architecture & Features
-
-### Component Structure
-
-The Overlay follows Bento's composition guidelines - using slots to pass state and handlers to children:
-
-```tsx
-import { useOverlay, useModalOverlay, useModal } from '@react-aria/overlays';
-import { useOverlayTrigger } from '@react-aria/overlays';
-import { useScrollLock } from '@bento/scroll-lock';
-import { Portal } from '@bento/portal';
-import { Backdrop } from '@bento/backdrop';
-import { DismissableLayer } from '@bento/dismissable-layer';
-import { FocusLock } from '@bento/focus-lock';
-import { Container } from '@bento/container';
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-import { withSlots, type Slots } from '@bento/slots';
-import React, { useRef, Children, isValidElement } from 'react';
-
-export interface OverlayProps extends Slots {
-  isOpen?: boolean;
-  defaultOpen?: boolean;
-  onOpenChange?: (isOpen: boolean) => void;
-  isDismissable?: boolean;
-  isKeyboardDismissDisabled?: boolean;
-  shouldCloseOnBlur?: boolean;
-  shouldCloseOnInteractOutside?: (element: Element) => boolean;
-  modal?: boolean;
-  children?: React.ReactNode;
-}
-
-export const Overlay = withSlots('BentoOverlay', function Overlay(props: OverlayProps) {
-  const {
-    isOpen: controlledOpen,
-    defaultOpen,
-    onOpenChange,
-    isDismissable = true,
-    isKeyboardDismissDisabled = false,
-    shouldCloseOnBlur = false,
-    shouldCloseOnInteractOutside,
-    modal = false,
-    children
-  } = props;
-
-  // Uncontrolled state management
-  const [internalOpen, setInternalOpen] = React.useState(defaultOpen ?? false);
-  const isOpen = controlledOpen ?? internalOpen;
-  const setIsOpen = React.useCallback((open: boolean) => {
-    if (controlledOpen === undefined) {
-      setInternalOpen(open);
-    }
-    onOpenChange?.(open);
-  }, [controlledOpen, onOpenChange]);
-
-  const overlayRef = useRef<HTMLDivElement>(null);
-  const triggerRef = useRef<HTMLElement>(null);
-
-  // React Aria hooks
-  const { overlayProps } = useOverlay({
-    onClose: () => setIsOpen(false),
-    isOpen,
-    isDismissable,
-    isKeyboardDismissDisabled,
-    shouldCloseOnBlur,
-    shouldCloseOnInteractOutside
-  }, overlayRef);
-
-  const { modalProps, underlayProps } = modal
-    ? useModalOverlay(
-        { isOpen, onClose: () => setIsOpen(false), isDismissable },
-        overlayRef
-      )
-    : { modalProps: {}, underlayProps: {} };
-
-  const { modalProps: hideContentProps } = useModal();
-
-  // Bento hooks
-  useScrollLock({ isDisabled: !isOpen || !modal });
-
-  const { props: processedProps } = useProps(props, {
-    isOpen,
-    modal,
-    isDismissable
-  });
-
-  const dataAttributes = useDataAttributes({
-    open: isOpen,
-    modal,
-    dismissable: isDismissable
-  });
-
-  // Extract children by slot
-  const childArray = Children.toArray(children);
-  const triggerChild = childArray.find((child) =>
-    isValidElement(child) && child.props.slot === 'trigger'
-  );
-  const contentChild = childArray.find((child) =>

-  );
-  const backdropChild = childArray.find((child) =>

-  const triggerProps = triggerChild && isValidElement(triggerChild)
-    ? useOverlayTrigger({ type: 'dialog' }, { isOpen, setOpen: setIsOpen }, triggerRef).triggerProps
-    : {};
-
-  if (!isOpen) {
-    // Render only trigger when closed
-    return triggerChild ? (
-      React.cloneElement(triggerChild as React.ReactElement, {
-        ...triggerProps,
-        ref: triggerRef,
-        onClick: (e: React.MouseEvent) => {
-          setIsOpen(true);
-          triggerChild.props.onClick?.(e);
-        }
-      })
-    ) : null;
-  }
-
-  return (
-    <>
-      {/* Trigger when open */}
-      {triggerChild && React.cloneElement(triggerChild as React.ReactElement, {
-        ...triggerProps,
-        ref: triggerRef,
-        'aria-expanded': true
-      })}
-
-      {/* Overlay content portaled */}
-      <Portal>
-        {/* Backdrop for modal overlays */}
-        {modal && (
-          <Backdrop
-            {...underlayProps}
-            slot="backdrop"
-            slots={processedProps.slots?.backdrop}
-          />
-        )}
-
-        {/* Custom backdrop if provided */}
-        {backdropChild && React.cloneElement(backdropChild as React.ReactElement, {
-          ...underlayProps,
-          slot: 'backdrop'
-        })}
-
-        {/* Dismissable layer wraps content */}
-        <DismissableLayer
-          {...overlayProps}
-          slot="dismissable"
-          slots={{
-            root: {
-              ...overlayProps,
-              ...processedProps.slots?.content
-            }
-          }}
-        >
-          <FocusLock
-            contain
-            restoreFocus
-            autoFocus
-            slot="focus-lock"
-            slots={{
-              root: {
-                ref: overlayRef
-              }
-            }}
-          >
-            <Container
-              {...processedProps}
-              {...dataAttributes}
-              {...hideContentProps}
-              {...modalProps}
-              slot="content"
-              slots={processedProps.slots?.content}
-            >
-              {contentChild ? (
-                React.cloneElement(contentChild as React.ReactElement, {
-                  slot: 'content'
-                })
-              ) : (
-                // Fallback: render non-slot children as content
-                childArray.filter(child =>
-                  !isValidElement(child) ||
-                  !['trigger', 'backdrop'].includes(child.props.slot)
-                )
-              )}
-            </Container>
-          </FocusLock>
-        </DismissableLayer>
-      </Portal>
-    </>
-  );
-});
-```
-
-### State Distribution via Slots
-
-Following Bento's composition guidelines, state and handlers are passed via slots to children:
-
-```tsx
-// Usage - all children use slot attributes
-<Overlay isOpen={isOpen} onOpenChange={setIsOpen} modal>
-  <Button slot="trigger">Open</Button>
-  <Backdrop slot="backdrop" />
-  <Container slot="content">
-    <Text>Content</Text>
-  </Container>
-</Overlay>
-```
-
-The component distributes:
-- `triggerProps` (from useOverlayTrigger) to `slot="trigger"` children
-- `underlayProps` (from useModalOverlay) to `slot="backdrop"` children
-- `overlayProps` (from useOverlay) to `slot="content"` children via DismissableLayer
-- `modalProps` (from useModal) to content container
-
-## Accessibility Highlights
-
-The Overlay primitive inherits React Aria's excellent accessibility features:
-
-- **ARIA roles**: Automatically applies appropriate roles (`dialog`, `alertdialog`) when used with React Aria's useDialog hook
-- **Modal state**: Uses `aria-modal="true"` for modal overlays (via useModalOverlay)
-- **Focus management**: Implements proper focus trapping via the FocusLock primitive
-- **Keyboard support**:
-  - Escape key to dismiss
-  - Tab navigation contained within the overlay
-  - Return focus to trigger element on close
-- **Screen reader announcements** for overlay state changes
-- **Proper handling of focus order** with multiple overlays (via React Aria's OverlayContainer)
-
-For mobile accessibility specifically:
-- Touch targets follow accessibility guidelines (minimum 44×44px)
-- Screen reader gestures are properly supported
-- Visible focus indicators are maintained for keyboard users
-
-## Internationalization, RTL, and Mobile Considerations
-
-The Overlay primitive is designed to work across different languages and layouts:
-
-- **RTL support**: The overlay positioning and animations work correctly in right-to-left layouts
-- **Mobile considerations**:
-  - Larger touch targets for mobile interactions
-  - Special handling for iOS Safari to prevent background content scrolling
-  - Support for mobile gestures (swipe to dismiss)
-  - Adjustments for virtual keyboard appearance
-  - Responsive sizing and positioning
-
-- **Internationalization**: The component handles text expansion from different languages by using flexible layouts
-

-## Competitive Research
-
-We conducted comprehensive research across major component libraries to identify the best approaches to overlay implementation:
-
-### React Aria
-
-React Aria provides a robust set of hooks for building accessible overlays:
-
-- **useOverlay**: Manages ARIA attributes and keyboard interactions
-- **useModalOverlay**: Adds modal-specific behaviors like backdrop interaction
-- **useModal**: Hides content outside overlay container from screen readers
-- **usePreventScroll**: Manages scroll locking with excellent cross-browser support
-- **useOverlayPosition**: Supports positioning relative to trigger elements
-- **useOverlayTrigger**: Connects trigger elements to overlays
-
-React Aria excels at accessibility but has a more imperative API that requires additional work to fit into Bento's composable component model.
-
-### Radix UI
-
-Radix UI offers a highly composable dialog component:
-
-```jsx
-// Radix UI approach
-<Dialog.Root>
-  <Dialog.Trigger />
-  <Dialog.Portal>
-    <Dialog.Overlay />
-    <Dialog.Content>
-      <Dialog.Title />
-      <Dialog.Description />
-      <Dialog.Close />
-    </Dialog.Content>
-  </Dialog.Portal>
-</Dialog.Root>
-```
-
-Strengths:
-- Excellent composition model
-- Good animation support via data attributes
-- Solid accessibility
-
-Weaknesses:
-- Some mobile edge cases
-- Occasional focus management issues in complex scenarios
-
-### Ark UI (Park UI foundation)
-
-Ark UI provides a flexible, store-based approach:
-
-```jsx
-// Ark UI approach
-const dialog = useDialogStore();
-
-<Dialog.Root store={dialog}>
-  <DialogHeading>Title</DialogHeading>
-  <DialogDescription>Description</DialogDescription>
-  <div>Content</div>
-  <DialogCloseTrigger>Close</DialogCloseTrigger>
-</Dialog.Root>
-```
-
-Strengths:
-- Powerful, flexible API
-- Excellent composition
-- Strong accessibility
-
-Weaknesses:
-- More complex API with steeper learning curve
-- Less direct React Aria integration
-
-### Headless UI
-
-Headless UI offers a simpler approach with good animation integration:
-
-```jsx
-// Headless UI approach
-<Transition show={isOpen}>
-  <Dialog onClose={setIsOpen}>
-    <Dialog.Overlay />
-    <Dialog.Title>Title</Dialog.Title>
-    <Dialog.Description>Description</Dialog.Description>
-    <div>Content</div>
-  </Dialog>
-</Transition>
-```
-
-Strengths:
-- Simplicity
-- Good animation integration
-- Solid accessibility
-
-Weaknesses:
-- Less flexible
-- Fewer customization options
-
-Our approach leverages React Aria for accessibility excellence while providing Bento's composable slot-based API for maximum flexibility.
-
-## Code Examples
-
-### Basic usage
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Button } from '@bento/button';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-

-          <Button onClick={() => setIsOpen(false)}>Close</Button>
-        </Container>
-      </Overlay>
-    </>
-  );
-}
-```
-

-import { Text } from '@bento/text';
-
-function OverlayWithTrigger() {
-  return (

-  );
-}
-```
-
-### Custom backdrop
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-import { Backdrop } from '@bento/backdrop';
-
-function CustomBackdrop() {
-  const [isOpen, setIsOpen] = useState(false);
-
-  return (
-    <Overlay isOpen={isOpen} onOpenChange={setIsOpen} modal>
-      <Backdrop
-        slot="backdrop"
-        className="custom-backdrop"
-        style={{ backgroundColor: 'rgba(0, 0, 0, 0.8)' }}
-      />
-      <Container slot="content">
-        <Text>Content with custom backdrop</Text>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-### Non-modal overlay (popover-like)
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-
-function NonModalOverlay() {
-  const [isOpen, setIsOpen] = useState(false);
-
-  return (
-    <Overlay
-      isOpen={isOpen}
-      onOpenChange={setIsOpen}
-      modal={false}
-      slots={{
-        content: {
-          style: { position: 'absolute', top: '100%', left: 0 }
-        }
-      }}
-    >
-      <Container slot="content">
-        <Text>Popover-like overlay</Text>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-### Dropdown inside modal (nested layers with CSS variables)
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-import { Button } from '@bento/button';
-import { useStackLayer } from '@bento/stack-orchestration';
-import { useRef, useState } from 'react';
-
-function ModalWithDropdown() {
-  const [modalOpen, setModalOpen] = useState(true);
-  const [dropdownOpen, setDropdownOpen] = useState(false);
-
-  const modalRef = useRef<HTMLDivElement>(null);
-
-  // Only modal registers with stack orchestration
-  const { zIndex: modalZIndex } = useStackLayer({
-    type: 'modal',
-    mfeId: 'my-mfe',
-    isOpen: modalOpen,
-    elementRef: modalRef,
-    priority: 100
-  });
-
-  return (
-    <Overlay isOpen={modalOpen} onOpenChange={setModalOpen}>
-      <Container
-        slot="content"
-        ref={modalRef}
-        style={{
-          zIndex: modalZIndex,
-          // CSS variable set automatically by useStackLayer
-          // --layer-z-index: modalZIndex
-        }}
-      >
-        <Text>Modal Content</Text>
-
-        {/* Dropdown trigger */}
-        <Button onClick={() => setDropdownOpen(!dropdownOpen)}>
-          Open Dropdown
-        </Button>
-
-        {/* Dropdown uses CSS calc() - no registration needed */}
-        {dropdownOpen && (
-          <Container
-            style={{
-              zIndex: 'calc(var(--layer-z-index) + 10)', // Automatically 5010 if modal is 5000
-              position: 'absolute',
-              top: '100%',
-              left: 0
-            }}
-          >
-            <Text>Dropdown content appears above modal</Text>
-            <Button onClick={() => setDropdownOpen(false)}>Close</Button>
-          </Container>
-        )}
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-**Key Points:**
-- Only modal registers with stack orchestration
-- Stack orchestration sets `--layer-z-index` CSS variable automatically
-- Dropdown uses `calc(var(--layer-z-index) + 10)` - no registration needed
-- CSS handles z-index calculation automatically
-- Simple, performant, uses standard CSS features
-
-### Animation with render props
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-
-function AnimatedOverlay() {
-  const [isOpen, setIsOpen] = useState(false);
-
-  return (
-    <Overlay
-      isOpen={isOpen}
-      onOpenChange={setIsOpen}
-      modal
-      slots={{
-        content: {
-          className: ({ state }) =>
-            state.open ? 'animate-in' : 'animate-out'
-        },
-        backdrop: {
-          className: ({ state }) =>
-            state.open ? 'fade-in' : 'fade-out'
-        }
-      }}
-    >
-      <Container slot="content">
-        <Text>Animated overlay</Text>
-      </Container>
-    </Overlay>
-  );
-}
-```

-## UI Patterns That Will Use Overlay
-
-The Overlay primitive serves as a foundation for various UI patterns:
-
-1. **Modals**: Full-screen or centered dialogs requiring user interaction
-2. **Drawers**: Side panels or bottom sheets that slide in from edges
-3. **Popovers**: Small overlays that appear near trigger elements
-4. **Tooltips**: Information overlays on hover/focus
-5. **Lightboxes**: Full-screen image/media viewers
-6. **Toast notifications**: Temporary messages appearing above content
-7. **Loading overlays**: Spinner or progress indicators during async operations
-8. **Context menus**: Dropdown menus with positioning logic
-
-Each of these patterns can be built by composing the Overlay primitive with additional behavior and styling, demonstrating the primitive's flexibility and reusability.

-# Overlay Primitive PDR
-
-## Purpose
-
-The Overlay primitive provides a foundational building block for creating layered UI experiences where content appears above the main application view. It serves as a blank canvas that teams can use to build modals, drawers, popovers, tooltips, and other overlay-based patterns.
-
-The Overlay primitive addresses several key scenarios:
-
-- Displaying content that requires immediate user attention or action
-- Creating focused interaction spaces that temporarily obscure or highlight main content
-- Supporting mobile-first patterns like drawers, sheets, and bottom panels
-- Enabling rich compositional patterns through layering of UI elements
-- Managing multiple simultaneous overlays with proper stacking and focus management
-
-This primitive will typically be consumed by:
-- Application developers building modal interfaces or drawers
-- Component authors creating specialized dialog components
-- Teams building loading indicators or notification systems
-- Any UI pattern requiring a visual layer between content and application
-
-### Unique Attributes
-
-The Overlay primitive differs from similar components in these key ways:
-
-- **Pure foundation**: Unlike most dialog components that combine multiple concerns, the Overlay provides only the backdrop, focus management, and dismissal behavior, allowing maximum composition flexibility
-- **Slot-based composition**: Follows Bento's slot system - consumers provide components as children, overlay passes state/handlers via slots
-- **Portal rendering**: Automatically renders content outside the DOM hierarchy via a Portal primitive
-- **Focus management**: Integrated focus trapping capabilities via FocusLock primitive that follow WAI-ARIA best practices
-- **Scroll locking**: Cross-browser scroll management that prevents background content scrolling
-- **Overlay stacking**: Built-in support for managing multiple simultaneous overlays with proper z-index and focus management
-- **Accessibility-first**: Built on React Aria's `useModalOverlay` and `useOverlay` hooks, ensuring WCAG compliance
-
-## Primitive Composition
-
-The Overlay primitive composes several standalone reusable primitives, maximizing code sharing across the Bento ecosystem:
-
-### Core Primitive Packages
-
-Each primitive is its own package following Bento's architecture:
-
-- **@bento/portal**: Handles DOM rendering placement (see `portal-primitive.mdx`)
-- **@bento/focus-lock**: Contains keyboard focus within a boundary (already documented in `focus-lock-primtive.mdx`)
-- **@bento/scroll-lock**: Prevents background scrolling (see `scroll-lock-primitive.mdx`)
-- **@bento/backdrop**: Provides visual backdrop that sits behind content (see `backdrop-primitive.mdx`)
-- **@bento/dismiss-button**: Accessible dismiss functionality (see `dismiss-button-primitive.mdx`)
-- **@bento/overlay-stack**: Manages multiple simultaneous overlays (see `overlay-stack-primitive.mdx`)
-- **@bento/container**: Base primitive for polymorphic rendering
-
-### Overlay Component Structure
-
-The Overlay is a single component that accepts children with slot attributes. Consumers provide the actual components (Button, Backdrop, etc.) and Overlay passes state/handlers via slots:
-
-```tsx
-<Overlay>
-  <Button slot="trigger">Open</Button>
-  <Backdrop slot="backdrop" />
-  <Container slot="content">
-    <Text>Overlay content</Text>
-    <DismissButton slot="close">Close</DismissButton>
-  </Container>
-</Overlay>
-```
-
-The Overlay component:
-- Manages state (open/close)
-- Passes trigger props via `slot="trigger"`
-- Passes backdrop props via `slot="backdrop"`
-- Passes content props via `slot="content"`
-- Passes close handler via `slot="close"`
-
-### React Aria Integration
-
-All primitives build directly upon React Aria's accessibility-focused hooks:
-
-- **useModalOverlay**: For backdrop and modal behavior
-- **useOverlay**: For core overlay behavior, dismissal, and accessibility
-- **useOverlayTrigger**: For trigger elements (props passed via slots)
-- **usePreventScroll**: For scroll locking (used via ScrollLock primitive)
-- **FocusScope**: For focus containment (used via FocusLock primitive)
-

-- Any overlay-based pattern
-
-## React Aria or External Hook Integration
-
-### Why React Aria?
-
-After extensive research of different overlay implementations, React Aria stands out as the optimal foundation:
-
-1. **Accessibility excellence**: React Aria is built from the ground up with accessibility as the primary focus, ensuring WCAG compliance
-
-2. **Comprehensive feature set**: React Aria provides a complete solution for overlay functionality:
-   - Focus management with `FocusScope` component
-   - Scroll locking with `usePreventScroll`
-   - Backdrop interaction with `useModalOverlay`
-   - Trigger management with `useOverlayTrigger`
-
-3. **Battle-tested in production**: Used extensively in Adobe's product ecosystem, ensuring robust performance in real-world applications
-
-4. **Excellent mobile support**: Handles complex mobile edge cases that other libraries miss, including iOS Safari scroll handling
-
-5. **Active maintenance**: Regular updates and community support ensure the library stays current with browser changes and accessibility standards
-
-### Hooks Used
-
-- **useOverlayTriggerState**: State management for overlay open/close state from @react-stately/overlays
-- **useModalOverlay**: Provides modal-specific props and accessibility attributes
-- **useOverlay**: Core overlay behavior (dismissal, keyboard handling)
-- **useOverlayTrigger**: Connects trigger elements to overlays (props passed via slots)
-- **usePreventScroll**: Prevents background scrolling (wrapped in ScrollLock primitive)
-
-No additional logic is needed beyond React Aria's implementation - it handles all edge cases for overlay behavior across devices.
-
-## Architecture & Features
-
-### State Management
-
-The Overlay uses React Aria's `useOverlayTriggerState` for state management, supporting both controlled and uncontrolled modes:
-
-- **Controlled**: `isOpen` and `onOpenChange` props
-- **Uncontrolled**: `defaultOpen` prop
-
-### Dismissal Behavior
-
-The overlay supports multiple dismissal patterns:
-
-- **Click outside**: Dismissable by clicking the backdrop (controlled by `isDismissable`)
-- **Escape key**: Keyboard dismissal (controlled by `isKeyboardDismissDisabled`)
-- **Programmatic**: Can be closed via state updates or DismissButton with `slot="close"`
-
-### Modal vs Non-Modal
-
-The overlay can operate in two modes:
-
-- **Modal** (`isModal={true}`): Blocks interaction with background content, uses `aria-modal="true"` (only when topmost)
-- **Non-Modal** (`isModal={false}`): Does not block background interaction, useful for tooltips and popovers
-
-### Portal Rendering
-
-All overlay content is rendered via the Portal primitive, ensuring proper z-index stacking and avoiding DOM hierarchy issues.
-
-### Focus Management
-
-Focus is managed through the FocusLock primitive which:
-- Traps focus within the overlay when open (only topmost when stacked)
-- Returns focus to the trigger element when closed
-- Handles initial focus placement
-- Manages focus order for accessibility
-
-### Scroll Locking
-
-Background scrolling is prevented via the ScrollLock primitive, which:
-- Prevents body scrolling when overlay is open
-- Handles iOS Safari edge cases
-- Maintains scroll position for restoration
-
-## Overlay Stacking Support
-
-A critical requirement is handling multiple simultaneous overlays (modals, drawers, popovers) **across multiple micro front-end applications**. The Overlay primitive integrates with `@bento/overlay-stack` to provide **peer-to-peer cross-bundle orchestration**.
-
-**Important**: There is **no host application** required - MFEs coordinate directly with each other through DOM and browser APIs.
-
-### Stack Management Challenges
-
-When multiple overlays are open simultaneously across different JavaScript bundles (micro frontends), coordination becomes critical:
-
-1. **Visual stacking (z-index)**: Which overlay appears on top - cannot rely on render order
-2. **Cross-bundle communication**: No shared JavaScript memory - must coordinate through DOM/browser APIs
-3. **Peer-to-peer coordination**: No host application - MFEs must coordinate directly with each other
-4. **Version compatibility**: Different MFEs may use different Bento versions (v1, v2, v3) simultaneously
-5. **Priority system**: Priority-based stacking where higher priority overlays appear on top
-6. **Keyboard focus**: Which overlay receives focus based on priority, not just z-index
-7. **ARIA attributes**: Proper `aria-modal` and `aria-hidden` attributes coordinated across bundles
-
-### UX Patterns for Multiple Overlays
-
-**Pattern 1: Sequential Dismissal**
-- Closing topmost overlay returns focus to next overlay below
-- Users dismiss overlays in reverse order of appearance
-- Each overlay maintains its own state independently
-- **Most common pattern** - used by default
-
-**Pattern 2: Cascade Dismissal**
-- Closing a parent overlay closes all child overlays
-- Useful for modal dialogs opened from other modals
-- Requires explicit parent-child relationships via props
-- **Optional pattern** - requires custom implementation
-
-**Pattern 3: Independent Stacks**
-- Overlays of different types (modal, tooltip, popover) stack independently
-- Each type has its own z-index base
-- Focus remains within each type's stack
-- **Automatic** - handled by overlay-stack primitive
-
-### Implementation
-
-The `@bento/overlay-stack` primitive provides **peer-to-peer cross-bundle orchestration**:
-
-- **Peer-to-peer coordination**: MFEs coordinate directly - no host application required
-- **Leader election**: One MFE instance becomes leader and coordinates stacking (based on version)
-- **Simple communication**: Uses Custom Events only - no persistence needed
-- **In-memory state**: All state is ephemeral and resets on page refresh (correct behavior)
-- **Version-aware**: Handles different Bento versions (v1, v2, v3) running simultaneously
-- **Priority system**: Priority-based stacking where higher priority overlays appear on top
-- **Automatic z-index calculation**: Based on priority, type, and timestamp (not just insert order)
-- **Focus management**: Only topmost overlay traps focus, coordinated across bundles
-- **ARIA coordination**: Only topmost modal has `aria-modal="true"`, lower modals get `aria-hidden="true"`
-- **Universal pattern**: Works for any competing UI layer (overlays, toasts, growls, tours)
-
-**Key difference**: This isn't just React state management - it's a peer-to-peer orchestration system that works when MFEs can't share JavaScript memory and don't have a host application.
-
-See `overlay-stack-primitive.mdx` for detailed implementation including micro frontend scenarios and version compatibility.
-
-### Nested Overlays (Dropdowns in Modals) - CSS Variables!
-
-When a dropdown or popover is rendered inside a modal, it's **automatically nested** using CSS custom properties:
-
-```tsx
-import { Overlay } from '@bento/overlay';
-import { Select } from '@bento/select';
-
-function ModalWithDropdown() {
-  return (
-    <Overlay>
-      {/* Overlay sets --layer-z-index: 4000 */}
-      <Container slot="content">
-        <Text>Modal Content</Text>
-
-        {/* Dropdown uses calc(var(--layer-z-index) + 1) */}
-        <Select>
-          <Dropdown /> {/* Automatically z-index: 4001 */}
-        </Select>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-**How it works:**
-- `Overlay` sets CSS variable `--layer-z-index` on its element
-- Nested layers detect parent CSS variable via `getComputedStyle`
-- Nested layers use `calc(var(--layer-z-index) + 1)` for relative z-index
-- CSS inheritance handles everything automatically
-- **Zero configuration** - standard web platform feature!
-
-**Key points:**
-- ✅ Uses CSS custom properties (standard web platform)
-- ✅ No React Context or manual tracking needed
-- ✅ Works across all frameworks (React, Vue, vanilla JS)
-- ✅ Automatic inheritance through DOM tree
-- ✅ Can force global with `forceGlobal={true}` if needed
-
-### Example: Multiple Overlays (Same Bundle)
-
-```tsx
-import { OverlayStackProvider } from '@bento/overlay-stack';

-### Example: Cross-Bundle Orchestration (Micro Frontends - No Host)
-
-```tsx
-// MFE A (Bento v2): Product Tour
-import { useOrchestratedLayer } from '@bento/overlay-stack';
-import { Overlay } from '@bento/overlay';
-
-function ProductTourMFE() {
-  const { ref, zIndex, isTopmost } = useOrchestratedLayer({
-    type: 'tour',
-    priority: 250, // Low priority (0-1000 scale)
-    isOpen: true,
-    mfeId: 'product-tour-mfe',
-    version: '2.1.0', // Bento version
-  });
-
-  return (
-    <Overlay isOpen={true}>
-      <Container slot="content" ref={ref} style={{ zIndex }}>
-        Product Tour (may be behind cookie consent)
-      </Container>
-    </Overlay>
-  );
-}
-
-// MFE B (Bento v1): Legal/Cookie Consent
-function CookieConsentMFE() {
-  const { ref, zIndex, isTopmost } = useOrchestratedLayer({
-    type: 'modal',
-    priority: 1000, // Critical priority (highest)
-    isOpen: true,
-    mfeId: 'legal-mfe',
-    version: '1.2.0', // Older Bento version, still works
-  });
-
-  // Even though v1 is older, it gets topmost due to priority
-  // v2 instance becomes leader (higher version) and calculates stack
-  return (
-    <Overlay isOpen={true}>
-      <Container
-        slot="content"
-        ref={ref}
-        style={{ zIndex }}
-        aria-modal={isTopmost ? 'true' : undefined}
-      >
-        Cookie Consent (always on top due to critical priority)
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-The overlay-stack primitive automatically:
-- **Peer-to-peer coordination**: MFEs coordinate directly, no host needed
-- **Leader election**: Highest version MFE becomes leader and coordinates
-- **Version compatibility**: Different Bento versions (v1, v2, v3) interoperate
-- **Priority-based stacking**: Higher priority overlays appear on top (cookie consent wins)
-- **Sets `aria-modal="true"`** only on topmost modal (cookie consent)
-- **Sets `aria-hidden="true"`** on lower overlays (product tour)
-- **Works even when bundles load in different orders**
-- **Handles competing toasts/growls from different MFEs and versions**
-
-## Accessibility Highlights
-
-The Overlay primitive inherits React Aria's excellent accessibility features:
-
-- **ARIA roles**: Automatically applies appropriate roles (`role="dialog"` for modals)
-- **Modal state**: Uses `aria-modal="true"` for modal overlays (only topmost when stacked)
-- **Focus management**: Implements proper focus trapping via FocusLock primitive (only topmost traps)
-- **Keyboard support**:
-  - Escape key to dismiss (unless disabled)
-  - Tab navigation contained within the overlay
-  - Return focus to trigger element on close
-- **Screen reader announcements**: Proper handling of focus order and overlay state
-- **Hidden content**: Background content is properly hidden from screen readers when modal
-- **Stacking awareness**: Lower overlays receive `aria-hidden="true"` when covered by topmost
-
-## Internationalization, RTL, and Mobile Considerations
-
-The Overlay primitive is designed to work across different languages and layouts:
-
-- **RTL support**: The overlay positioning and animations work correctly in right-to-left layouts
-- **Mobile considerations**:
-  - Touch targets follow accessibility guidelines
-  - Screen reader gestures are properly supported
-  - Visible focus indicators maintained for keyboard users
-  - iOS Safari scroll locking handled correctly
-  - Virtual keyboard handling for mobile inputs
-
-- **Internationalization**: The component handles text expansion from different languages by using flexible layouts

-## Competitive Research
-
-We conducted comprehensive research across major component libraries:
-
-### React Aria
-
-React Aria provides hooks for building accessible overlays:
-- **useModalOverlay**: Manages ARIA attributes and keyboard interactions
-- **useOverlay**: Core overlay behavior
-- **useOverlayTrigger**: Connects triggers to overlays
-
-**Strengths:**
-- Exceptional accessibility
-- Robust focus management
-- Strong mobile support
-
-**Adopted as foundation**: We use React Aria as our base, enhancing with Bento's slot-based composition model.
-
-### Radix UI
-
-Radix UI offers a highly composable dialog component with compound components:
-
-```tsx
-<Dialog.Root>
-  <Dialog.Trigger />
-  <Dialog.Portal>
-    <Dialog.Overlay />
-    <Dialog.Content>
-      <Dialog.Title />
-      <Dialog.Description />
-      <Dialog.Close />
-    </Dialog.Content>
-  </Dialog.Portal>
-</Dialog.Root>
-```
-
-**Differences:**
-- Radix uses compound components (forbidden in Bento)
-- Bento uses slot-based system (consumers provide components as children)
-
-**Insights adopted:**
-- Data attribute-based state for styling
-- Portal rendering pattern
-
-### Ark UI / Park UI
-
-Ark UI (headless) and Park UI (styled) provide similar patterns to Radix:
-
-**Differences:**
-- Also use compound components
-- Bento's slot system is more flexible
-
-**Insights adopted:**
-- Separation of concerns (backdrop, content, trigger)
-

-      </Container>
-    </Overlay>
-  );
-}
-```
-
-### Drawer pattern
-
-```tsx

-          width: '400px'
-        }}
-      >
-        <nav>
-          <Text>Navigation</Text>
-          <ul>
-            <li><a href="/">Home</a></li>
-            <li><a href="/about">About</a></li>

-        </nav>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-### Multiple overlays with stacking
-
-```tsx
-import { OverlayStackProvider } from '@bento/overlay-stack';
-
-function MultipleOverlays() {
-  const [firstOpen, setFirstOpen] = useState(false);
-  const [secondOpen, setSecondOpen] = useState(false);
-
-  return (
-    <OverlayStackProvider>
-      <Button onClick={() => setFirstOpen(true)}>Open First Overlay</Button>
-
-      <Overlay isOpen={firstOpen} onOpenChange={setFirstOpen}>
-        <Backdrop slot="backdrop" />
-        <Container slot="content">
-          <Text>First Overlay</Text>
-          <Button onClick={() => setSecondOpen(true)}>Open Second Overlay</Button>
-          <DismissButton slot="close">Close First</DismissButton>
-        </Container>
-      </Overlay>
-
-      <Overlay isOpen={secondOpen} onOpenChange={setSecondOpen}>
-        <Backdrop slot="backdrop" />
-        <Container slot="content">
-          <Text>Second Overlay</Text>
-          <Text>This overlay appears above the first one.</Text>
-          <DismissButton slot="close">Close Second</DismissButton>
-        </Container>
-      </Overlay>
-    </OverlayStackProvider>
-  );
-}
-```
-
-The overlay-stack primitive automatically handles:
-- Higher z-index for second overlay (4010 vs 4000)
-- Focus trapping in topmost overlay
-- ARIA attributes (only topmost has aria-modal="true")
-- Focus restoration when second closes

-# Primitive Design Review (PDR): Overlay
-
-## Purpose
-
-Provide a flexible, accessible overlay layer (backdrop + content container) for building modals, drawers, sheets, popovers, and other layered experiences — especially important for mobile. The Overlay offers foundational behavior while remaining a blank, composable canvas.
-
-## Foundations and Requirements
-
-- MUST integrate React Aria for a11y behaviors:
-  - `useModalOverlay` (modal semantics, underlay/backdrop interactions, ESC/outside-click dismissal)
-  - `useOverlayTrigger` (trigger relationship)
-  - `useOverlay` / `useOverlayPosition` (non-modal patterns)
-  - `usePreventScroll` (via Scroll Lock primitive)
-- MUST follow composition guidelines at `composition-guidelines.mdx`:
-  - Pass state/handlers via slots (no custom context for these concerns)
-  - Semantic slot names
-  - Prefer `Container` for structure and polymorphism
-- MUST use existing primitives where applicable: `@bento/container`, `@bento/text`, `@bento/focus-lock`, `@bento/scroll-lock`, `@bento/visually-hidden`
-- MUST expose data-* attributes to support styling, animations, testing
-- MUST be composable: consumers can replace pieces via slots without losing behavior
-
-## What this enables in the system
-
-- Modals and Dialogs (centered and full-screen)
-- Drawers and Sheets (edge-anchored)
-- Popovers, Menus, and Dropdowns (non-modal overlays)
-- Lightboxes/Image viewers
-- Toast/Notification stacks (layered z-index management)
-
-## Stacking and multiple overlays
-
-- Use `Stack` (React Aria overlay container wrapper) at app/feature boundaries so overlays share a stacking context without custom providers.
-- Top-most is determined by portal/DOM order within the same `Stack`.
-- ESC and outside interactions are handled by the top-most overlay when using `useModalOverlay`.
-- Underlying overlays remain inert/aria-hidden per React Aria.
-
-Recommended CSS token-based z-index (no runtime stack): assign `z-index` via tokens such as `--z-popover`, `--z-overlay`, `--z-modal` to `content/backdrop` slots.
-
-Example with two modals:
-
-```tsx
-import { Stack } from '@bento/stack';
-
-function TwoModals() {
-  const [a, setA] = React.useState(false);
-  const [b, setB] = React.useState(false);
-  return (
-    <Stack>
-      <Overlay open={a} onOpenChange={setA}>
-        <Container slot="trigger" as="button" onClick={() => setA(true)}><Text>Open A</Text></Container>
-        <Container slot="backdrop" />
-        <Container slot="content" style={{ zIndex: 'var(--z-modal)' }}><Text>A</Text></Container>
-      </Overlay>
-
-      <Overlay open={b} onOpenChange={setB}>
-        <Container slot="trigger" as="button" onClick={() => setB(true)}><Text>Open B</Text></Container>
-        <Container slot="backdrop" />
-        <Container slot="content" style={{ zIndex: 'var(--z-modal)' }}><Text>B</Text></Container>
-      </Overlay>
-    </Stack>
-  );
-}
-```
-
-### Priority & escalation (e.g., cookie consent)
-
-Use a dedicated `Stack` with a higher z-index token and target it from `Portal` (or an `Overlay` prop that forwards to Portal). This avoids runtime managers while guaranteeing precedence.
-
-```tsx
-import { Stack } from '@bento/stack';
-
-function App() {
-  return (
-    <>
-      <Stack id="stack-root-default" />
-      <Stack id="stack-root-critical" className="stack-root-critical" />
-      <Shell />
-    </>
-  );
-}
-
-function CookieConsent() {
-  const [open, setOpen] = React.useState(true);
-  const critical = typeof document !== 'undefined' ? document.getElementById('stack-root-critical') : undefined;
-  return (
-    <Overlay open={open} onOpenChange={setOpen}>
-      {/* ensure this mounts into the critical root */}
-      {open && critical && (
-        <Portal container={critical}>
-          <Container slot="backdrop" className="underlay" />
-          <Container slot="content" style={{ zIndex: 'var(--z-critical-overlay)' }}>
-            <Text as="h2">We use cookies</Text>
-            <Container as="button" onClick={() => setOpen(false)}><Text>Accept</Text></Container>
-          </Container>
-        </Portal>
-      )}
-    </Overlay>
-  );
-}
-
-/* CSS */
-.stack-root-critical { z-index: var(--z-critical-overlay); }
-```
-
-## Additional primitives required
-
-We will reuse existing PDRs where present and introduce only the missing ones. Each primitive must use `bento/slots`, `use-props`, and `data-attributes`.
-
-- Already exist:
-  - Focus management: `@bento/focus-lock` (see `focus-lock-primtive.mdx`)
-  - Scroll locking: `@bento/scroll-lock` (see `scrolllock-pdr.mdx`)
-  - Screen reader helpers: `@bento/visually-hidden` (see `visually-hidden-primitive.mdx`)
-
-- New to add:
-  - Portal: `@bento/portal` — controlled DOM mounting outside regular tree
-  - Dismiss Button: `@bento/dismiss-button` — wrapper for React Aria DismissButton
-
-Stacking policy: rely on React Aria overlay container semantics via `OverlayRoot` and DOM/portal order. No custom application context for stacking.
-
-## Slot map and state
-
-| Slot          | Purpose                                 | Required | Default |
-|---------------|------------------------------------------|----------|---------|
-| `root`        | Top-level container                      | Yes      | Yes     |
-| `backdrop`    | Underlay behind content                  | No       | Yes     |
-| `content`     | Foreground content container             | Yes      | Yes     |
-| `trigger`     | Element that opens/closes the overlay    | No       | No      |
-| `close`       | Close control inside content             | No       | No      |
-
-Data attributes (example set; exact mapping below):
-- `data-state`: `open` | `closed`
-- `data-open`: `true` | `false`
-- `data-modal`: `true` | `false`
-- `data-animated`: `true` | `false`
-- `data-placement`: e.g. `center`, `top`, `bottom`, `left`, `right`, `bottom-start`, etc.
-// no separate `data-topmost`; rely on DOM/portal order and React Aria overlay container semantics
-
-## Props
-
-| Prop            | Type                                | Default | Description                                                                 |
-|-----------------|-------------------------------------|---------|-----------------------------------------------------------------------------|
-| `open`          | `boolean`                           | `false` | Controlled open state                                                       |
-| `onOpenChange`  | `(open: boolean) => void`           | —       | Called to request state changes (open/close)                                |
-| `modal`         | `boolean`                           | `true`  | Modal behavior (backdrop, focus containment, prevent scroll)                |
-| `isDismissable` | `boolean`                           | `true`  | Passed to React Aria for outside‑click/ESC dismissal when modal             |
-| `children`      | `React.ReactNode`                   | —       | Consumer content; placed into slots based on `slot` prop                    |
-| `slots`         | `Record<string, SlotOverride>`      | —       | Slot overrides per composition guidelines                                     |
-
-Notes:
-- For non‑modal positioning, use React Aria `useOverlayPosition` at the call site and pass its props into the `content` slot (see Non‑modal section).

-- Object slot: merges props into the default element
-- Function slot: replaces the default element with custom render
-
-## Data attributes per slot
-
-| Slot       | Attributes                                                                     | Notes                                                     |
-|------------|---------------------------------------------------------------------------------|-----------------------------------------------------------|
-| `root`     | `data-state` (`open`/`closed`), `data-open`, `data-modal`                      | Set by `useDataAttributes` on the root container          |
-| `backdrop` | `data-open`, `data-modal`                                                      | Mirrors state for styling/animations                      |
-| `content`  | `data-open`, `data-modal`, optional `data-placement` (consumer‑provided)       | For non‑modal, placement/positioning is consumer‑controlled |
-| `trigger`  | —                                                                               | Overlay merges React Aria trigger props; no data-* needed |
-| `close`    | —                                                                               | Visible close is consumer‑provided                        |
-
-## Composition model
-
-- Parent composite (Overlay) owns state and passes handlers via slots
-- Children (primitives like `Container`, `Button`, `Text`) receive state through slots
-- No custom context for overlay state; when deep state is needed, prefer environment (`Box.env`) per guidelines
-
-## Implementation outline (React Aria + Bento)
-
-The Overlay can be used in modal or non-modal modes. For modal, `useModalOverlay` provides `overlayProps` and `underlayProps`. Per composition guidelines, pass state and handlers via slots.
-
-```tsx
-import React, { useRef } from 'react';
-import { withSlots } from '@bento/slots';
-import { useProps } from '@bento/use-props';
-import { useDataAttributes } from '@bento/use-data-attributes';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-import { useModalOverlay, useOverlayTrigger } from '@react-aria/overlays';
-
-export interface OverlayProps {
-  open?: boolean;
-  modal?: boolean;
-  onOpenChange?: (open: boolean) => void;
-}
-
-export const Overlay = withSlots('BentoOverlay', function Overlay(args: OverlayProps) {
-  const { props: processedProps } = useProps(args, {});
-  const { open = false, modal = true, onOpenChange } = processedProps;
-
-  const triggerRef = useRef<HTMLButtonElement | null>(null);
-  const { triggerProps } = useOverlayTrigger(
-    { type: modal ? 'dialog' : 'popover' },
-    { isOpen: open, open: () => onOpenChange?.(true), close: () => onOpenChange?.(false) },
-    triggerRef
-  );
-
-  const { overlayProps, underlayProps } = useModalOverlay(
-    { isOpen: open, isDismissable: true },
-    { isOpen: open, close: () => onOpenChange?.(false) }
-  );
-
-  const data = useDataAttributes({ state: open ? 'open' : 'closed', open, modal });
-
-  // Logic-only pattern: pass state/handlers via slots
-  return (
-    <Container
-      {...processedProps}
-      {...data}
-      slot="root"
-      slots={{
-        trigger: { ...triggerProps, ref: triggerRef },
-        backdrop: open ? { ...underlayProps, 'data-modal': modal, 'data-open': open } : null,
-        content: open
-          ? { ...overlayProps, 'data-modal': modal, 'data-open': open }
-          : null
-      }}
-    />
-  );
-});
-```
-
-Notes:
-- State/handlers flow through slots. Consumers can supply children in these slots to customize visuals while retaining behavior.
-- For non-modal overlays, prefer `useOverlay` + optional `useOverlayPosition` and skip `ScrollLock`.
-
-## Usage examples
-
-### Basic modal with backdrop (slots-only)
-
-```tsx
-function BasicModal() {
-  const [open, setOpen] = React.useState(false);
-  return (
-    <Overlay open={open} onOpenChange={setOpen}>
-      <Container slot="trigger" as="button" onClick={() => setOpen(true)}>
-        <Text>Open</Text>
-      </Container>
-      <Container slot="backdrop" className={({ state }) => state.open ? 'backdrop-open' : 'backdrop-closed'} />
-      <Container slot="content" className="dialog">
-        <Text as="h2">Title</Text>
-        <Text>Description</Text>
-        <Container slot="close" as="button" onClick={() => setOpen(false)}>
-          <Text>Close</Text>
-        </Container>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-### Drawer (bottom sheet) pattern (slots-only)
-
-```tsx
-<Overlay open={open} onOpenChange={setOpen}>
-  <Container slot="trigger" as="button" onClick={() => setOpen(true)}>
-    <Text>Open Drawer</Text>
-  </Container>
-  <Container slot="backdrop" className="underlay" />
-  <Container
-    slot="content"
-    className={({ state }) => state.open ? 'sheet sheet-in' : 'sheet sheet-out'}
-    data-placement="bottom"
-  >
-    <Text as="h2">Sheet</Text>
-    <Text>Content</Text>
-  </Container>
-  <Container slot="close" as="button" onClick={() => setOpen(false)}>
-    <Text>Close</Text>
-  </Container>
-</Overlay>
-```
-
-### Wrapper pattern with Focus and Scroll lock
-
-```tsx
-function ModalWithInfra() {
-  const [open, setOpen] = React.useState(false);
-  return (
-    <Overlay open={open} onOpenChange={setOpen}>
-      <Container slot="trigger" as="button" onClick={() => setOpen(true)}><Text>Open</Text></Container>
-
-      {/* Optional infrastructure as children when open */}
-      {open && (
-        <Portal>
-          <ScrollLock />
-          <FocusLock contain restoreFocus autoFocus />
-        </Portal>
-      )}
-
-      <Container slot="backdrop" className="underlay" />
-      <Container slot="content" className="dialog"><Text>Content</Text></Container>
-    </Overlay>
-  );
-}
-```
-
-## Non‑modal layered surfaces (Popover, Dropdown, Menu)
-
-- For non-modal patterns, omit the `backdrop` slot and set `modal={false}`
-- Use React Aria `useOverlay` and `useOverlayPosition` to manage dismissal and positioning
-- Focus containment (`FocusLock`) is typically not used for simple popovers; rely on return focus behavior as needed
-
-```tsx
-import { useOverlay, useOverlayPosition } from '@react-aria/overlays';
-
-export function PopoverLike(props) {
-  const triggerRef = React.useRef<HTMLButtonElement>(null);
-  const overlayRef = React.useRef<HTMLDivElement>(null);
-  const [open, setOpen] = React.useState(false);
-
-  const { overlayProps } = useOverlay({ isOpen: open, onClose: () => setOpen(false), isDismissable: true }, overlayRef);
-  const { overlayProps: positionProps } = useOverlayPosition({
-    targetRef: triggerRef,
-    overlayRef,
-    placement: 'bottom-start',
-    offset: 8
-  });
-
-  return (
-    <Overlay open={open} onOpenChange={setOpen} modal={false}>
-      <Container slot="trigger" as="button" ref={triggerRef} onClick={() => setOpen((v) => !v)}>
-        <Text>Open</Text>
-      </Container>
-      <Container slot="content" ref={overlayRef} {...overlayProps} {...positionProps} style={{ zIndex: 'var(--z-popover)' }}>
-        <Text>Popover content</Text>
-      </Container>
-    </Overlay>
-  );
-}
-```
-
-## Micro‑frontend orchestration usage
-
-When pages host multiple MFEs that may emit competing layered experiences, render within a host-provided `Stack` and coordinate container access via the Stack orchestrator (see `stack-primitive.mdx`). Flow:
-
-1) MFE requests a container for a given type (e.g., `modal`, `popover`, `toast`)
-2) Host grants with a container id (e.g., `stack-root-default` / `stack-root-critical`)
-3) MFE portals overlay content to the granted container (slots still drive visuals)
-4) On close, MFE releases the request id
-
-```tsx
-const [container, setContainer] = React.useState<HTMLElement | null>(null);
-React.useEffect(() => {
-  if (!open) return;
-  let activeId = '';
-  (async () => {
-    const el = await requestStack('modal', 'stack-root-default');
-    setContainer(el);
-    activeId = 'req_current';
-  })();
-  return () => window.dispatchEvent(new CustomEvent('bento:stack:release', { detail: { requestId: activeId } }));
-}, [open]);
-
-<Overlay open={open} onOpenChange={setOpen}>
-  {open && container && (
-    <Portal container={container}>
-      <Container slot="backdrop" />
-      <Container slot="content"><Text>Overlay content</Text></Container>
-    </Portal>
-  )}
-</Overlay>
-```
-
-### React Aria PortalProvider (per‑MFE)
-
-If your MFE uses React Aria components, wrap its subtree with `UNSAFE_PortalProvider` and pass the container granted by Stack so all React Aria overlays (dialogs, popovers, tooltips, toasts) portal into the same root. See [PortalProvider](https://react-spectrum.adobe.com/react-aria/PortalProvider.html).
-
-```tsx
-import { UNSAFE_PortalProvider } from 'react-aria';
-
-function MyMfe({ container }) {
-  return (
-    <UNSAFE_PortalProvider getContainer={() => container}>
-      {/* Overlay, Popover, Toast components here */}
-    </UNSAFE_PortalProvider>
-  );
-}
-```
-
-### No-host environments
-
-- If no host provides a Stack, MFEs participate in P2P orchestration:
-  - Elect a temporary leader using BroadcastChannel/localStorage lease
-  - Leader creates required `Stack` roots if absent and relays bus messages
-  - All MFEs use the same versioned message envelope; older Bento versions are bridged by the leader via DOM events
-- Fallbacks:
-  - If bus not available, components may portal to `document.body`, but must set conservative z-index and avoid exclusive modality; add telemetry to detect conflicts
-
-## Complete example: Modal with slots, ScrollLock, FocusLock, DismissButton, Stack, PortalProvider
-
-```tsx
-import * as React from 'react';
-import { Stack } from '@bento/stack';
-import { Overlay } from '@bento/overlay';
-import { Container } from '@bento/container';
-import { Text } from '@bento/text';
-import { Portal } from '@bento/portal';
-import { FocusLock } from '@bento/focus-lock';
-import { ScrollLock } from '@bento/scroll-lock';
-import { DismissButton } from '@bento/dismiss-button';
-import { UNSAFE_PortalProvider } from 'react-aria';
-
-function App() {
-  return (
-    <>
-      {/* Provide a stacking root (host or P2P leader may create this) */}
-      <Stack id="stack-root-default" />
-      <MyMfe />
-    </>
-  );
-}
-
-function MyMfe() {
-  const [container, setContainer] = React.useState<HTMLElement | null>(null);
-  React.useEffect(() => {
-    setContainer(document.getElementById('stack-root-default'));
-  }, []);
-  if (!container) return null;
-
-  return (
-    <UNSAFE_PortalProvider getContainer={() => container}>
-      <CompleteModal container={container} />
-    </UNSAFE_PortalProvider>
-  );
-}
-
-function CompleteModal({ container }: { container: HTMLElement }) {
-  const [open, setOpen] = React.useState(false);
-  return (
-    <Overlay open={open} onOpenChange={setOpen}>
-      {/* Trigger provided via slot; Overlay merges triggerProps */}
-      <Container slot="trigger" as="button" onClick={() => setOpen(true)}>
-        <Text>Open modal</Text>
-      </Container>
-
-      {/* All layered pieces portal into the shared Stack container */}
-      {open && (
-        <Portal container={container}>
-          {/* Body scroll is prevented while open */}
-          <ScrollLock />
-          {/* Focus contained within modal, restores on close */}
-          <FocusLock contain restoreFocus autoFocus>
-            {/* Underlay/backdrop; Overlay injects React Aria underlayProps via slots */}
-            <Container
-              slot="backdrop"
-              className={({ state }) => (state.open ? 'backdrop-open' : 'backdrop-closed')}
-              style={{ zIndex: 'var(--z-modal)' }}
-            />
-
-            {/* Foreground content; Overlay injects overlayProps via slots */}
-            <Container slot="content" className="dialog" style={{ zIndex: 'var(--z-modal)' }}>
-              {/* Screen-reader accessible dismiss controls at start/end */}
-              <DismissButton onDismiss={() => setOpen(false)} />
-
-              <Text as="h2">Complete Modal</Text>
-              <Text>All infrastructure in one example.</Text>
-
-              {/* Visible close button for sighted users */}
-              <Container as="button" onClick={() => setOpen(false)}>
-                <Text>Close</Text>
-              </Container>
-
-              <DismissButton onDismiss={() => setOpen(false)} />
-            </Container>
-          </FocusLock>
-        </Portal>
-      )}
-    </Overlay>
-  );
-}
-```
-
-## Data attributes and styling
-
-Recommended attributes exposed by `Overlay` and its slots:
-- `data-state`: `open`/`closed`
-- `data-open`: `true`/`false`
-- `data-modal`: `true`/`false`
-- `data-placement`: semantic placement for positioning/animations
-- `data-animated`: when transitions are active
-// no `data-topmost`; topmost is determined by portal/DOM order and React Aria overlay container
-
-Example CSS-based animations:
-
-```css
-[data-bento-component="BentoOverlay"] [slot="content"][data-state="open"] { /* fade in */ }
-[data-bento-component="BentoOverlay"] [slot="content"][data-state="closed"] { /* fade out */ }
-```
-
-## Accessibility
-
-- React Aria provides: ESC dismiss, outside click handling (when dismissable), `aria-modal`, focus containment, restore focus to trigger
-- Use `FocusLock` to contain focus; `ScrollLock` to prevent background scroll (critical on iOS Safari)
-- Include an accessible close control; for screen reader dismissal affordances, use `@bento/dismiss-button`
-- For nested overlays, React Aria's overlay container semantics ensure correct accessibility of the top-most overlay within the container
-
-## Mobile considerations
-
-- Prevent background scroll (`@bento/scroll-lock`)
-- Support bottom sheets and responsive sizing
-- Handle virtual keyboard; ensure content remains reachable when keyboard is visible
-- Larger tap targets for close actions
-
-## Performance
-
-- Mount overlay subtree only when open
-- Prefer opacity/transform-only animations
-- Memoize expensive children; lazy-load heavy content
-
-## Competitive analysis (facts summary)
-
-- React Aria: hook-based a11y foundation (`useModalOverlay`, `useOverlay`, `useOverlayTrigger`, `usePreventScroll`), robust mobile support and focus management
-- Radix UI: composable Dialog/Popover primitives, strong data-attribute animation pattern, portal-based layering
-- Ark UI (used by Park UI): headless components for Dialog/Popover, flexible composition across frameworks
-- Headless UI: Dialog + Transition; simple, a11y-compliant, good animation integration
-- Material UI: `Modal`/`ModalManager` for stacking and focus/scroll handling; comprehensive, opinionated
-
-Implications for Bento:
-- Adopt React Aria for core modal/overlay semantics
-- Prefer React Aria overlay container + portal order for stacking (no custom context)
-- Provide Portal primitive for controlled DOM placement
-- Provide Dismiss Button for SR-friendly dismissal
-- Leverage data attributes to drive CSS animations, aligning with ecosystem patterns
-
-## Decision checklist
-
-- [ ] What state/handlers are exposed via slots (trigger, content, close)?
-- [ ] Is modal vs non-modal behavior explicit and surfaced via data-attributes?
-- [ ] Are focus and scroll behavior delegated to `@bento/focus-lock` and `@bento/scroll-lock`?
-- [ ] Is Portal used for controlled placement (stacking by DOM/portal order)?
-- [ ] Do slots map semantically (backdrop, content, trigger, close)?
-- [ ] Are accessibility affordances (dismiss button, ESC, restore focus) present?

-# Use Stack Primitive PDR
-
-## Purpose
-
-The useStack hook provides **peer-to-peer orchestration** for managing competing
-UI layers across multiple micro front-end (MFE) applications running on the same
-page. It coordinates overlays, toasts, growls, popovers, and other layered UI
-patterns when different JavaScript bundles need to display content
-simultaneously.
-
-There is **no host application** - coordination happens between MFEs themselves
-through the DOM and browser APIs.
-
-The useStack hook addresses several critical scenarios:
-
-- **Cross-bundle coordination**: Multiple independent JavaScript bundles
-  displaying UI layers simultaneously
-- **Version compatibility**: Different MFEs may use different versions of Bento
-  (v1, v2, v3) simultaneously
-- **No shared memory**: Bundles cannot access each other's JavaScript memory/state
-- **Peer-to-peer communication**: MFEs coordinate directly without a central authority
-- **Universal orchestration**: Works for any layered UI pattern (overlays,
-  toasts, growls, product tours, etc.)
-- **Insert order independence**: Z-index coordination works even when MFEs load
-  in different orders
-
-This hook will typically be consumed by:
-
-- Overlay components that need stack management
-- Toast/growl notification systems
-- Product tour experiences
-- Legal/cookie consent modals
-- Live chat overlays
-- Any UI layer that may compete with others from different MFEs
-
-### Unique Attributes
-
-The useStack hook differs from typical stacking solutions in these key ways:
-
-- **Peer-to-peer**: No host application required - MFEs coordinate between each other
-- **Leader election**: One MFE instance becomes leader and coordinates stacking
-- **Simple communication**: Uses Custom Events only
-- **In-memory state**: All state is ephemeral - resets on page refresh
-- **Version-aware**: Handles different versions (v1, v2, v3) running simultaneously
-
-## The Micro Frontend Challenge
-
-When multiple independent JavaScript bundles run on the same page, traditional
-React state management fails:
-
-**❌ Doesn't work:**
-```tsx
-// This only works within a single bundle
-const [stack, setStack] = useState([]);
-```
-
-**Real-world scenarios that break:**
-
-1. **Product Tour vs Cookie Consent**
-   - MFE A (Bento v2) launches product tour (overlay + popovers)
-   - MFE B (Bento v1) must show cookie consent modal (legal requirement)
-   - Both need to be visible - which should be topmost?
-   - **Problem**: No way to coordinate between v1 and v2 bundles
-
-2. **Live Chat vs Host Modal**
-   - Live chat MFE wants to show chat overlay
-   - Another MFE needs to show critical modal
-   - Which experience should users interact with?
-   - **Problem**: No host to arbitrate
-
-3. **Competing Growls**
-   - MFE A (v2) sends "Order confirmed" toast
-   - MFE B (v3) sends "Payment processed" toast
-   - Without coordination, they overlap/stack incorrectly
-   - **Problem**: Different versions don't know about each other
-
-4. **Version Incompatibility**
-   - MFE using Bento v1 cannot coordinate with MFE using Bento v3
-   - Each version might use different protocols
-   - **Problem**: Need backward compatibility
-
-### Why Traditional Approaches Fail
-
-1. **React Context**: Only works within a single bundle
-2. **Shared state**: JavaScript scope memory isn't shared across bundles
-3. **Z-index, order, and stacking context race conditions**: Last bundle to
-  render wins, not necessarily the most important, especially with the web moving
-  towards async bundle loading and dynamic rendering.
-4. **No authority system**: No way to determine which MFE's UI should take priority
-
-ecture Overview
-
-### Peer-to-Peer Coordination
-
-The Layer Orchestrator uses a **distributed event system** to coordinate between
-all instances:

-```
-
-Key Difference from Leader Election Pattern:
-- **No leader election**: All instances are equal
-- **Shared global state**: All instances read/write to `window.__bentoLayerRegistry`
-- **Event sync**: All broadcast, all listen, all update
-- **Independent calculation**: Each calculates z-index from synced state
-
-Problems with leader election (consensus.js pattern):
-
-1. **Single point of failure**: If leader unmounts, coordination stops
-2. **State loss**: Leader's state not shared, lost on leader change
-3. **Complexity**: Leader election adds complexity and race conditions
-4. **Re-election delays**: Time between leader unmount and new leader causes coordination gaps
-
-Benefits of distributed approach:
-1. **No single point of failure**: All instances function independently
-2. **Immediate sync**: State changes broadcast to all, all update immediately
-3. **Simpler**: Each instance maintains state, syncs via events
-4. **Resilient**: If one instance fails, others continue coordinating
-
-## Performance Considerations
-
-- **Event-driven**: No polling, uses native DOM events
-- **In-memory only**: No storage persistence - state resets on page refresh (as it should)
-- **Lazy leadership**: Only leader does calculations
-- **Minimal overhead**: Simple Map-based storage in memory
-- **Automatic cleanup**: Unmounting removes state naturally
-
-## React Aria or External Hook Integration
-
-The Layer Orchestrator works **alongside** React Aria's overlay system:
-
-- **React Aria**: Handles accessibility, focus management within a single MFE
-- **Layer Orchestrator**: Coordinates across MFEs for z-index and state
-- **Distributed Events**: Provides peer-to-peer coordination without host
-
-They complement each other:
-1. Layer Orchestrator determines z-index across all MFEs (via distributed events)
-2. React Aria handles focus/accessibility within that MFE's overlay
-3. Layer Orchestrator manages ARIA attributes coordination (only topmost gets aria-modal)
-4. React Aria manages ARIA attributes within the controlled overlay
-
-## Architecture & Features
-
-### No Host Setup Required
-
-**No host application setup is required.** Each MFE:
-
-1. Includes Bento layer-orchestrator in its bundle
-2. Creates registry on mount (singleton per MFE)
-3. Broadcasts registrations/unregistrations via CustomEvents
-4. Listens to all broadcasts and updates local registry
-5. Calculates z-index independently from synced registry
-
-### State Synchronization
-
-> Note: The `__bentoLayerRegistry` is used as example variable name for the
-> shared global registry. Expect this to be finalized in the actual
-> implementation.
-
-**Two mechanisms ensure state sync:**
-
-1. **Shared Global Registry (`window.__bentoLayerRegistry`)**: All MFEs on the
-  same page share the same JavaScript `window` object, so they can all read/write
-  to a shared global Map. This provides immediate visibility - when MFE A writes
-  to the registry, MFE B can read it directly.
-
-2. **CustomEvents (Coordination)**: Events notify all instances when the
-  registry changes, triggering z-index recalculation. Events are lightweight
-  notifications - the actual state is in the shared global.
-
-**Sync flow:**
-
-```mermaid
-sequenceDiagram
-    participant A as MFE A
-    participant Registry as window.__bentoLayerRegistry
-    participant Events as CustomEvents
-    participant B as MFE B
-    participant C as MFE C
-
-    A->>Registry: Register layer (write)
-    A->>Events: Broadcast bento:layer:register
-    Events->>B: Event received
-    Events->>C: Event received
-    B->>Registry: Read registry state
-    C->>Registry: Read registry state
-    B->>B: Calculate z-index
-    C->>C: Calculate z-index
-    Note over A,C: All MFEs read from same<br/>global registry → same z-index
-```
-
-1. MFE A registers layer → writes to `window.__bentoLayerRegistry` → broadcasts event
-2. MFE B receives event → reads from `window.__bentoLayerRegistry` → calculates z-index
-3. MFE C receives event → reads from `window.__bentoLayerRegistry` → calculates z-index
-4. All MFEs read from same global registry → all calculate same z-index
-
-### Race Condition Handling
-
-**Problem**: Two MFEs register simultaneously
-
-**Solution**: Timestamp-based ordering
-- Each registration includes `timestamp: Date.now()`
-- When priority/type are equal, newer (higher timestamp) wins
-- Timestamps ensure deterministic ordering across all instances
-
-### New Instance Joining
-
-When a new MFE mounts:
-1. Initializes `window.__bentoLayerRegistry` if it doesn't exist (or uses existing one)
-2. Reads current state directly from the shared global registry
-3. Starts listening to events for future changes
-4. Immediately has full registry state and can coordinate
-
-**No sync needed**: Since the registry is in shared global memory, new instances automatically see all existing layers as soon as they access `window.__bentoLayerRegistry`.
-
-## API Design
-
-```tsx
-function ProductTour({ steps, currentStep }) {
-  const isOpen = currentStep < steps.length;
-  const { zIndex, isTopmost } = useStack({
-    id: 'product-tour',
-    type: 'tour',                         //
-    priority: 'low',
-    isOpen,
-  });
-
-  // If we lose topmost status, pause the tour
-  useEffect(() => {
-    if (!isTopmost && isOpen) showPausedMessage('Cookie consent required. Tour will resume.');
-  }, [isTopmost, isOpen]);
-
-  if (!isOpen) return null;
-
-  return (
-    <>
-      <Overlay isOpen={isTopmost}>
-        <Container as="div" slot="backdrop" style={{ zIndex: zIndex - 1 }} />
-        <Popover style={{ zIndex }}>
-          <Text as="p">Step {currentStep + 1} of {steps.length}</Text>
-        </Popover>
-      </Overlay>
-    </>
-  );
-}
-```
-
-### Layer Types
-
-All layer types are orchestrated, not just overlays:
-
-| Type    | Base Z | Use Cases                  | Stacking Behavior          |
-|---------|--------|----------------------------|----------------------------|
-| Overlay | 600    | Modals, dialogs            | Block lower priorities     |
-| Drawer  | 500    | Side panels, sheets        | Block lower priorities     |
-| Chat    | 400    | Live chat widgets          | Non-blocking, persistent   |
-| Tour    | 300    | Product tours, onboarding  | Non-blocking, dismissable  |
-| Toast   | 200    | Notifications, growls      | Stack vertically, no overlap|
-| Popover | 100    | Tooltips, dropdowns        | Non-blocking, contextual   |
-
-### Priority Levels
-
-| Priority  | Level | Use Cases                           | Examples                    |
-|-----------|-------|-------------------------------------|----------------------------|
-| Critical  | 4     | Legal requirements, critical errors | Cookie consent, GDPR, errors|
-| High      | 3     | Important user flows                | Checkout, payment, forms   |
-| Normal    | 2     | Standard interactions               | Modals, drawers, settings  |
-| Low       | 1     | Non-blocking feedback               | Tours, tips, marketing     |
-
-
-## Registry
-
-```typescript
-registry.configure({
-  layers: {
-    'overlay': 600,
-    ...
-  },
-  policies: {
-    'legal-compliance': 'critical',    // Legal always wins
-    'security-mfe': 'critical',        // Security alerts
-    'checkout': 'high',                // Checkout flows
-    'product-catalog': 'normal',
-    'marketing': 'low'                 // Marketing content
-  }
-});
-```
-
-## Accessibility Highlights
-
-The Layer Orchestrator ensures accessibility across MFEs:
-
-- **ARIA modal coordination**: Only topmost modal gets `aria-modal="true"` (each instance calculates independently)
-- **Focus management**: Focus stays within the topmost MFE's overlay
-- **Screen reader behavior**: Only topmost layer is announced
-- **Keyboard navigation**: Escape key dismisses topmost layer first
-
-### Cross-MFE Focus
-
-When layer ordering changes:
-1. Previous topmost layer releases focus (returns to trigger)
-2. New topmost layer receives focus
-3. Screen reader announces new layer
-4. Keyboard events handled by new topmost layer
