   Kër Atelier — boutique en ligne (démo Zephyr)
   Parti pris assume : galerie claire, une seule ambiance. Un theme sombre
   subi rendait les photos de mobilier ternes et le tout un peu triste.
   Autonome : aucune requête externe, polices système, zéro dépendance.
   Les visuels produits sont dessinés en CSS (aucune image à charger).
