   Reproduction fidèle du prototype validé (prototype-allauch-v2-mobile.html).
   Trois actes plein écran : seuil (acte-0) / présence (acte-2) / coda (acte-3).
   Pilotée par dispositif.js (classes .acte-0/.acte-2/.acte-3 + .is-visible,
   #btnStart, .acte2-player*, #yt-player) et optin.js (#merciEmail*).
   N'utilise NI style.css NI dispositif.css NI reskin.css : feuille autonome.
