   Objectif : remettre le hero À propos en scène full-width avec vidéo fondue et PNG centré.
   - Deux colonnes en flux : texte à gauche, scène fondateur à droite.
   - Vidéo du hero étirée sur toute la largeur du hero, avec bords fondus, plus CTA final.
   - Logo SBI ghost warm metallic / bronze, fondu dans la scène.
   - PNG fondateur recentré dans la scène et masqué tant que Firebase ne l’a pas injecté.
   - Aucune bordure, aucun cadre visible, aucune forme parasite.
