 * Résidence du Quai : feuille de style du site public.
 * Charte graphique V1 (septembre 2026) : Bleu Quai #133459, Greige Résidence #AB9F95, Bleu Profond #0D2D51,
 * Brume #F4F2EF et beaucoup de blanc ; Inter (titres en Light, textes en Regular, libellés en Semibold espacé) ;
 * le filet vertical greige, la numérotation fine, les alignements à gauche ; ni dégradé, ni ombre portée, ni 3D.
 * Mise en page : une grille éditoriale en deux colonnes (5/12 à gauche pour les titres, 7/12 à droite pour le
 * contenu), même largeur pour l'en-tête et le contenu. Idée directrice conservée : la symétrie de l'immeuble
 * (deux appartements en miroir par étage) autour d'un axe, dans la façade et dans la plaque du haut de page.
