/* ==========================================================================
   MahjongKit — styles.css
   Material Design 3 (Expressive) tokens and components, written in plain CSS.
   One file for the whole site. No framework, no build step.

   To re-theme: change the color roles in section 1. Everything else uses
   those variables. Never type a hex color in a page.

   1. Color roles (light + dark)          7. Homepage
   2. Shape, type, motion, spacing         8. Article template + components
   3. Base and typography                  9. Section pages, search, 404
   4. Top app bar, navigation bar,        10. Flower Match game
      navigation drawer, footer           11. Motion, print
   5. Buttons, chips, cards, lists
   6. Tile motif
