/* ============================================================
   VILA-NOVA — Feuille de styles globale
   Plombier Chauffagiste / Serrurier Vitrier — Charvieu-Chavagneux
   ------------------------------------------------------------
   Ambiance : MODERNE / AUDACIEUX / COLORÉ — assumé.
   Source de vérité : content/brief-design.md (fait autorité).
   Override appliqué : le défaut « Artisan = Solide/Terrain,
   anthracite + orange sobre, Oswald + Open Sans » est ÉCARTÉ
   (trop classique). On vise énergie, contrastes francs, blocs
   dynamiques et animations au scroll soignées. L'audace porte
   sur le visuel ; les textes restent clairs et rassurants.

   Palette (brief) : anthracite #26292E + doré #C9A227 + teal #1FB6A6.
   3e couleur d'accent : TEAL #1FB6A6, choisi par le client
   (différenciant, tranche avec le site d'artisan classique).
   Typo : Space Grotesk (titres) + Inter (corps).
