Ajoute une couche de micro-animations sur tout le site

Deux courbes partagées dans lib/motion.ts, pour que le CSS et Framer
aient le même feeling, et quatre primitives que Tailwind ne sait pas
exprimer : reflet de bouton, halo qui suit le curseur, soulignement qui
se dessine, secousse d'erreur.

Nouveaux composants : Stagger (les collections se distribuent une par
une), Spotlight (trouve son parent tout seul, donc les cartes restent
des composants serveur), ScrollProgress, BackToTop, Parallax, Spinner,
CheckMark. Reveal accepte maintenant une direction.

Côté rendu : le trait de nav glisse d'un onglet à l'autre, les cartes
se soulèvent, le hero réagit au scroll, les piliers entrent en zig-zag,
la lightbox glisse dans le sens demandé et les formulaires répondent.

prefers-reduced-motion est respecté partout : Framer coupe via
useReducedMotion, le CSS via la media query déjà en place.

Le commit embarque aussi la réorganisation des composants par domaine
qui était en cours dans l'arbre de travail — les deux étaient trop
imbriquées pour être séparées proprement.
