   SIL Caunes Valley — feuille de style partagee
   Socle commun a toutes les pages : tokens, reset, header/nav, boutons,
   bande CTA, footer, utilitaires. Le style propre a chaque page vit dans un
   <style> en tete de cette page. Binome : assets/cards.css (effets de cartes).

   Refonte 2026-07 : sortie du framework DC (rendu React cote client) vers du
   HTML/CSS statique. Ce fichier remplace les styles inline dupliques.
