 * Lumis — socle visuel des pages statiques (légales, dépôt, page vidéo, partenaires, 404, merci).
 * Philosophie « Base » (système de design d'Uber) : monochrome strict (noir, blanc, gris), texte grand et lisible
 * (« Go big »), peu de choix (« Less is more »), noms par rôle, grille de 4 px, boutons pleins noirs, champs remplis.
 * Une seule police (Inter, auto-hébergée sous /fonts), aucune couleur d'accent : l'image et la vidéo apportent la couleur.
 * Le site vitrine React (web/site) reprend exactement les mêmes valeurs dans son thème Tailwind.
