Walkthrough

Updates package identifiers and versioning in the Android module, adds explicit Material 3 theme shapes and typography, extends theming with a new CompositionLocal for extended colors and integrates shapes into MaterialTheme. Multiple UI screens switch to default/top-app-bar color behaviors and revised card colors. Documentation and README sections are pruned or commented out. A metadata README is added.

Poem

I nibbled the badges, hid stars in the hay,
Painted new shapes where the corners lay.
Packed fresh colors in a pocket so light,
Cards and bars now glow just right.
With a hop to v1.0.0, I cheer—
“Ship-shape styling, carrot-clear!” 🥕✨
