 * ════════════════════════════════════════════════════════════════════
 * Stratégie "Premium Subtle" — refonte visuelle des 3 tiers ads
 * (Gold / Silver / Copper) :
 *   - Bordure 1px subtile + halo coloré tier (alpha 8-12%)
 *   - Ruban triangulaire plié en coin haut-droit (CSS only, pas d'image)
 *   - Hover lift (translateY -3px) + intensification du halo
 *   - Image dominante avec dégradé latéral pour transition fluide
 *   - Mobile-only inline copper card (le sticky lateral est invisible <1280px)
 * Aucune touche au code marketplace : ce fichier est uniquement consommé
 * par les classes appliquées dans GoldAdSlot, SilverAdSlot, StickyAds,
 * AdTemplatePreview.
