/* Andanza — andanza.net
   Tokens, type roles and component metrics come from docs/andanza-visual-system.md
   in the walkinGuide repo, mirrored in mobile/lib/core/design_tokens.dart,
   app_typography.dart and app_theme.dart. Change them there first.

   Fonts are self-hosted (OFL licences in fonts/): the app bundles the same two
   families, and serving them from here means no visitor request reaches a
   third-party font CDN. Weights 400 and 500 only — the system has no others. */
