   ════════════════════════════════════════════════════════════════════════════
   INTERDITS — viole brief Précision si réintroduit :
   - Glassmorphism (backdrop blur > 12px, transparence > 30 %)
   - Bento > 6 tiles, hover scale > 1.02, rounded-xl > 8px sauf .badge full
   - Glow rouge agressif sur boutons primary
   - Mesh gradient multicolor (indigo + vert + violet)
   - Emoji comme icônes UI (utiliser SVG inline)
   - Animations linear pour interactions (linear OK uniquement scroll-driven)
   - Couleurs pop : émeraude, indigo, fuchsia, cyan néon
   - drop-shadow > 32px ou alpha > 0.45
   - Animations `bottom` / `left` / `width` (utiliser `transform` only)
