/* ==========================================================================
   دور كمان — the brand on the web (Brand Book V2, docs/DESIGN.md).
   Tokens, base, and the few components every page shares: the button, the
   playing card, the pill, the header and the footer.

   Mirrors lib/theme/tokens.dart (AppPalette.forest / .brick). This file and
   nothing downstream holds a palette hex: pages and components name ROLES.
   One theme, like the app: it opens in forest whatever the phone says.
   Brick is a SECOND GROUND for a whole section (`.ground-brick`), never a
   colour on its own — the roles swap, the geometry does not.

   The rules the book sets, as the web keeps them:
   - Orange is ACTION only — the beta button. Never a heading, never
     decoration, never a link colour.
   - Depth without gloss: a solid, unblurred toy edge under cards and
     buttons; pressed things sink onto it. No blurred drop shadows.
   - Cream is the ink. Never pure white.
