   All Ads Market — système de verre (glassmorphism premium)
   Palette : fond marine profond quasi noir, panneaux de verre à chant
   lumineux diagonal (biseau chromé), accent or/ambre pour les CTA.
   Vocabulaire visuel calqué sur les références fournies (sphère chromée,
   plaques de verre à liseré argenté, glow diagonal type "Apple Liquid
   Glass") — même logique que le composant CxGlass déjà construit pour
   l'app CacaoC : chant complet + traînée diagonale, jamais un aplat plat.
