/* ----- Partenaires : double bandeau défilant en sens opposés -----
   CSS pur : chaque bandeau contient deux pistes identiques (la seconde
   aria-hidden) ; la piste défile de 0 à -100% en boucle. Pause au survol
   et au focus clavier ; désactivé si prefers-reduced-motion.
   Cartes de taille fixe, logos chargés d'emblée : la largeur des pistes ne
   dépend pas du chargement des images (sinon saut de l'animation). */
