Material 3
Material 3 (awake:ui:material3)
Material 3 components and theme contracts for Awake's retained Compose-shaped UI runtime.
This is separate from :awake:ui:shadcn: applications choose one component family for a screen
instead of mixing their visual policy. Generic layout, input, drawing, and modifier behavior remain
in :awake:compose:foundation.
The initial surface is Scaffold, with a Material color-scheme provider. Its top bar, bottom bar,
and floating action button are measured independently; the content slot receives their measured
insets rather than a guessed bar height.
