/* ==========================================================================
   WIVO web — the app's design system, ported to CSS.

   Nothing here is invented. Every token below is read directly out of
   app/lib/core/design/. Where the web needs something the app does not define
   (a fluid type scale, a link colour), it is DERIVED from these tokens — no
   foreign values.

     colours   → wivo_colors.dart
     type      → wivo_type.dart
     spacing   → wivo_spacing.dart
     buttons   → wivo_button.dart
     frame     → wivo_scaffold.dart

   Dark only. The app has no light mode ("this is a night-driving product, and
   the design commits to that" — wivo_theme.dart:7-8), so neither does the site.
   ========================================================================== */

/* --------------------------------------------------------------------------
   Fonts — served from this origin. NEVER from a CDN: a webfont CDN discloses
   the visitor's IP address to a third party on every page load, which for a
   product sold into Germany is a GDPR problem (and the app itself bundles the
   same files for the same reason — wivo_type.dart:5).

   All seven faces the app ships are declared. A browser downloads only the
   ones a rule actually uses, so the unused weights cost nothing.
