/* landing/style.css
   Shared document layout for /privacy, /terms, and /support. Visually descends
   from landing/index.html (which keeps its own inline styles — see the
   out-of-scope note there): same tokens, fonts, header/footer chrome.

   Palette: app design-system tokens (lib/design_systems/colors.dart) —
   `background` page surface, forest greens for headings, coinGold strictly
   as accent (link underlines), never text on light surfaces and never a
   large surface. One landing-only derivation flagged inline (text-muted). */
