   HUB VILLE — /ville/{ville}

   Direction : « carte-héros immersif ». Le héros est la carte de la ville
   (pins des projets par catégorie) surmontée d'un dégradé et du titre ; en
   dessous, une barre de filtres collante (catégories + recherche + compteur)
   et une grille de cards éditoriales. Conçu pour scaler d'1 projet à 200+.

   Dépendances : /styles/00-colors.css (tokens, alias sémantiques, dark mode).
   Famille visuelle : chip system topbar + glass canon + boutons de la fiche v2.
   Dark mode : uniquement les surfaces glass ; le reste suit les alias.
