/* Civadelia shared components.
   Loaded right after tokens.css. Built only from tokens, so every component
   follows the institution colour and dark mode automatically.

   Every class is prefixed ui- so nothing here collides with the legacy
   .btn / .card / .table / .co-* / .gs-* rules. Look: neutral and flat, with the
   brand colour reserved for primary actions, focus, links and highlights
   (decision 4). The stats row and quick-link cards follow the student and
   lecturer dashboard patterns (decision 10).
