/* ==========================================================================
   OwnVouch — Topograph design system (web)
   Ported 1:1 from the Flutter app: lib/theme/app_theme.dart (tokens) and
   lib/widgets/topo.dart (components). Warm sand paper, contour-line
   texture, terracotta accent, Zilla Slab + Azeret Mono.

   House rules, same as the app:
   - Ink surfaces are reserved for ceremonies. Don't reach for ink to make
     an ordinary section look important — it dilutes the signal.
   - No literal colours or font names in section rules. Use the role
     tokens below.
   - Cards are radius 20, controls are radius 12. Nothing in between.
   ========================================================================== */
