   8. MOUVEMENT
   Le mouvement accompagne la lecture, il ne la retarde jamais.
   - Apparition : data-reveal (un bloc) ou data-reveal-stagger (ses enfants en cascade) —
     fondu, montée et mise au point (flou → net). main.js retire les classes à la fin.
   - Médias : les visuels des cartes se posent (zoom arrière) à l'apparition, puis
     glissent légèrement au défilement (parallaxe, navigateurs compatibles).
   - Lumière au curseur, relief 3D, boutons magnétiques, sur-titres décodés,
     frise du processus : motion.js (styles dans les composants concernés).
   - Grain de film très léger sur toute la page, logotype géant du footer.
   Tout ce qui se déplace est coupé si l'utilisateur préfère moins d'animations.
