   MODAL UNIFIÉ — Système de modales responsive
   ================================================================
   Fichier centralisé pour TOUTES les modales du site.
   Backend (admin, user, pro) et Frontend (public).
   
   RÈGLE ABSOLUE : Ne JAMAIS redéfinir de styles modal inline 
   dans les pages. Utiliser uniquement ces classes.
   
   Classes principales :
     .modal-overlay        → fond overlay (blur + fond sombre)
     .modal-container      → boîte principale de la modale
     .modal-header         → en-tête (titre + bouton fermer)
     .modal-body           → contenu scrollable
     .modal-footer         → pied (boutons d'action)
   
   Tailles disponibles (via modificateur sur .modal-container) :
     .modal-sm             → max-width 400px (confirmations)
     .modal-md             → max-width 560px (formulaires simples)
     .modal-lg             → max-width 720px (formulaires moyens)
     .modal-xl             → max-width 960px (éditeurs complexes)
   
   Ouverture/Fermeture :
     Ajouter/retirer la classe .active sur .modal-overlay
