Rakuten's call-first messenger. Single-brand Viber Purple (#7360F2) outgoing bubbles, gray incoming (#EDEBF5 / #26232F), the three-state check receipt (gray → gray → violet #8F7DF7 seen), a purple→deep-violet (#59267C) free-call banner, and an aubergine-tinted (#121118) dark canvas.
The complete Viber design system — free. The framework-neutral DESIGN.md plus SwiftUI, Expo, and Jetpack Compose companions: screen-by-screen breakdown, full color & type system, component specs, motion curves, haptics, and a ready-to-paste AI-agent implementation prompt.
