/* KINOENGINE — LA COUCHE « FUTUR » (26/09/2026).
   Paul : « fais beaucoup plus design et futuriste, on est un site de ouf ».
   Posée PAR-DESSUS le système clair de la vitrine, sans le remplacer : la
   règle du 13/09 tient toujours — AUCUN FOND NOIR. Le futur ici, c'est la
   lumière : aurores qui dérivent, verre dépoli, bordures en dégradé qui
   brillent, halo qui suit la souris, grille de précision en filigrane.
   Tout mouvement s'éteint avec prefers-reduced-motion. */
