/*
 * Mini-site du projet de Bierwart (nom de travail : Résidence de la Forge) : feuille de style du site public.
 *
 * Direction : l'architecture de l'immeuble (briques gris clair, bardage en bois naturel, menuiseries anthracite, deux
 * volumes aux toits plats) et le nom de la rue (la Forge). Palette : cuivre #B4562B (accents, boutons, filets),
 * anthracite #24272B (textes, pied de page), pierre #EFEBE5 (fonds alternés), papier #FBFAF7 (fond de page).
 * Typographie : Fraunces (titres, serif chaleureuse à contraste marqué) et Manrope (textes, prix, boutons, libellés).
 * Gestes propres au site : le cadre décalé en cuivre autour des images (le volume en retrait de l'immeuble), le
 * pictogramme de l'immeuble qui situe l'étage de chaque appartement, le filet court en cuivre au-dessus des libellés,
 * le dernier mot des titres en cuivre. Aucun tiret cadratin nulle part.
