 * Bouton CTA fixe en bas d'écran mobile uniquement (≤ 768px) :
 *   - Apparait après scroll > 50vh (via .is-visible ajoutée par JS)
 *   - Disparait quand on est dans la section #cta-final (intersection observer)
 *   - Backdrop-filter blur + accent orange brique
 *   - Padding-bottom safe-area pour iPhones notch
