/* ==========================================================================
   PROJET MAKE — LAYOUT GÉNÉRAL
   --------------------------------------------------------------------------
   RÔLE :
   - Définir les tokens visuels communs (variables CSS) utilisés par le layout.
   - Styliser la structure globale : body, shell, main.
   - Styliser le header (desktop + mobile) et le footer du site.
   - Fournir une base stable commune à toutes les pages publiques.

   IMPORTANT :
   - Chargé globalement depuis app/Views/layouts/header.php.
   - Fonctionne avec :
       - app/Views/layouts/header.php
       - app/Views/layouts/footer.php
       - assets/js/ui.js (comportements header/footer)
       - assets/js/app.js (initialisation générale)
   - Ne doit PAS contenir de styles spécifiques à une page :
       - pas de .mk-* (home),
       - pas de .catalogue-*,
       - pas de .detail-*.
   - Les styles de page vivront dans des fichiers séparés
     (home.css, catalogue.css, product.css, etc.).
