/* ============================================================================
   MODULE CATALOGUE — styles (catalog.css)
   ----------------------------------------------------------------------------
   Couvre la page catalogue (catalogue.html) ET la fiche produit
   (produit.html). N'utilise QUE les tokens de css/base.css (couleurs, rayons,
   polices Sora + Inter déjà chargées) : aucune couleur ni police en dur, pour
   rester cohérent avec le reste du site. Chargé après base.css + nav.css +
   footer.css, avant rien d'autre — le module est autonome côté CSS aussi.
