Anime la page d'accueil : apparitions au défilement + étoiles en mouvement

- Composant Reveal (IntersectionObserver) + keyframes CSS : sections et grilles
  apparaissent en fondu/glissement, cartes en cascade (stagger). Respecte
  prefers-reduced-motion + repli no-JS.
- Étoiles (sparkles) : l'animation twinkle inclut désormais une dérive
  (translation) pour un mouvement nettement visible.
