Description: Maquette de refonte pour Piémontesi Savagnier SA, entreprise générale à Savagnier depuis 1908. Réalisations réelles avec avant / après animés, scènes 3D légères en three.js (chantier qui se construit au défilement, maison animée) avec repli statique sur mobile et en mouvement réduit. Aucune dépendance externe : polices système, scripts et médias embarqués. À l'activation, le thème crée les pages nécessaires si elles n'existent pas.
