   Téléphone d'abord : la vidéo 9:16 occupe l'écran, gros bouton WhatsApp, autres vidéos en dessous.
   Autonome (pas de ui.css) : la page n'a aucun script ; toujours claire (propriétaire 15/10/2026 : le site est
   clair par défaut, le système est ignoré — et cette page n'a pas de bouton « الوضع الداكن »).
