/* Refonte de la page mini-jeux : mêmes codes visuels que les cartes
   d'articles de l'accueil (.article-card) plutôt qu'un style générique
   "carte blanche + icône" qui ne correspondait pas à la DA du site —
   même grille responsive, même radius/ombre/hover, même animation
   d'entrée fadeInUp échelonnée. Comme les jeux n'ont pas de vraie photo
   de couverture, la zone image est remplacée par un bandeau dégradé aux
   couleurs de la marque + une grande icône (au lieu d'un simple badge
   d'icône). Le moteur de chaque jeu (dans .game-preview) n'est pas
   modifié ci-dessous. */
