/* ==========================================================================
   Sites de démonstration — feuille de style commune
   --------------------------------------------------------------------------
   Ces trois démos partagent la même structure mais PAS la même identité :
   chaque page redéfinit les variables ci-dessous dans son propre <style>.
   C'est exactement la méthode utilisée sur le site principal — et la preuve
   qu'un même socle bien construit donne des résultats très différents.

   Sommaire :
   1. Variables (redéfinies par chaque démo)
   2. Bandeau « démonstration »
   3. Bases et mise en page
   4. En-tête et navigation
   5. Hero
   6. Sections, cartes, listes
   7. Formulaire et pied de page
   8. Responsive
