Adds src/theme/tokens/sys/color/roles.ts with a roleToTone table keyed by (mode, contrast) and a buildScheme() function. LightTheme and DarkTheme replace their hand-duplicated color literals with a single buildScheme() call each. Output shape is identical; tone values match the existing hand-written spec.
Adds the 10 MD3 shape scale tokens to theme.shapes.*, ShapeCorners for directional variants, and cornersToStyle() for mapping to RN style props. Deprecates theme.roundness in favour of theme.shapes.
Adds 15 *Emphasized entries per M3 Design Kit: Display/Headline/TitleLarge/Body use Medium (500), TitleMedium/TitleSmall/Label use Bold (700). Adds weightBold to ref.typeface. Fixes displayLarge letterSpacing (0 -> -0.25) and bodyLarge letterSpacing (0.15 -> 0.5).
Adds theme.motion with two preset schemes (expressiveMotion default, standardMotion), M3 easing curves, and duration constants verified against the material.io spec. Includes toRawSpring() helper to convert the spec damping ratio to the raw coefficient expected by Animated.spring and Reanimated. Deprecates animation.defaultAnimationDuration in favour of theme.motion.duration.*. No component consumes the tokens yet.
- Delete src/deprecated.ts and all MD3*/DefaultTheme/useAppTheme re-exports - Remove createMaterialBottomTabNavigator and entire src/react-navigation/ directory - Remove theme.mode field from Theme type and DarkTheme definition - Remove ThemeBase type - Remove deprecated component props: FAB.small, Button.color, BottomNavigation BaseRoute.color - Remove Card adaptive dark mode logic (tonal surfaces handle dark theme in MD3) - Update example app and docs to use canonical names (Palette, LightTheme, DarkTheme) - Rename internal useAppTheme to _useTheme to avoid confusion with removed public symbol
