/* ═══ Synchro — vitrine publique v2 « Horizon » (20/10) ═══════════════════════════════════════════════════════════
   Une seule lumière par écran (l'horizon du héros, le bas des cartes de données, le trait coupé du final) sur un noir
   bleuté ; le produit en grand et en profondeur ; les chiffres réels posés comme des objets.
   Page autonome (rien d'externe ; legal.css/legal.js de /test pour les textes légaux). Mobile d'abord : 390 → 760
   (tablette, 8 col.) → 1100 (bureau, 12 col., conteneur 1200).
   Perf iPhone : animations transform/opacity seulement, aucun backdrop-filter sous 1100 px, images cuites en WebP.
   Apparitions : [data-r] (une par bloc) et [data-h] (entrée du héros) — sans JS, tout est visible. ═══ */
