/* ══════════════════════════════════════════════════════════════════════
   Vitrine Vistar — refonte (14/10/2026), alignée sur la refonte du portail
   (portail-refonte.css, docs/PLAN_REFONTE_PORTAIL_2026-10-14.md).
   Même langage : cadre brun-noir (en-tête, pied de page), feuille ivoire pour
   le contenu, Cormorant + DM Sans, filets bronze, micro-labels majuscules.
   Règles « pas de rendu IA » : filets plutôt qu'ombres, rayons courts
   (≤ 9 px, 12 px pour la feuille comme dans le portail), aucun dégradé ni
   lueur, de vraies images (photos, 3D, captures du portail), texte plutôt
   que pastilles-icônes.
   Les tokens --s-* reprennent les valeurs --pf-* du portail (thème clair) ;
   vistar-ds.css (chargé avant) fournit --serif et --sans.
