/* ─────────────────────────────────────────────────────────────
   FamilyStories Website — Shared Styles
   Color palette derived from the FamilyStories app (FsTokens):
   https://github.com/anomalyco/opencode/blob/main/familystories/lib/ui/design/fs_tokens.dart

   Maintainability guide:
   - All colors are CSS custom properties — edit :root once to update everywhere
   - Store links and support email are also CSS custom properties — easy to replace
   - Spacing uses a 4px base unit (r4, r8, r12, r16, r24, r32, r48)
   - Radius values match FsTokens (r8, r12, r16)
