======================================================================
   ISJIEE-NEXT / MAGAZSTARS -- VITRINE
   Direction "Maison de Membres" -- bleu nuit profond, or champagne pour
   l'action/récompense, émeraude pour la progression BAR. La chaleur vient
   d'un fond ivoire discret sur les cartes plutôt que d'un blanc pur, et
   d'une serif éditoriale (Fraunces) réservée aux titres -- signature
   typographique du sentiment "membre" plutôt que "produit SaaS".
   Signature de page : le "Chemin des 11 Niveaux" -- seul élément à porter
   une vraie animation continue (respiration douce). Tout le reste reste
   sobre : les transitions se déclenchent au survol, jamais en continu.
