/* =============================================================================
   Wegwijs met AI — Component Library (Handoff)
   =============================================================================
   Herbruikbare UI-klassen, gedistilleerd uit de design-system preview-kaarten.
   Alle tokens komen uit tokens.css (laad dat eerst).

   Volgorde:
   1. Buttons
   2. Forms (input, textarea, select, checkbox-card, toggle)
   3. Badges & chips (level, status, lesson-type, reward)
   4. Cards (generic, continue-card, lesson-row)
   5. Progress (bar, ring)
   6. Quiz feedback (correct / almost — niet-bestraffend)
   7. Utilities (.sr-only, .reading-max, focus ring helpers)

   BELANGRIJK:
   - Gebruik __geen__ hover-lift op knoppen (minder animatie-ruis tijdens leren).
   - Minimum 44px hoogte op alle interactieve elementen (touch-target).
   - Focus-ring zichtbaar op alle varianten (keyboard-nav voor senioren).
