   EC@RT — UNITY ZONES

   Remplace : zone_02.css, zone-02-unity.css
   et leurs équivalents pour les zones 03, 08, etc.

   v1.2 — correctif reload tablette :
   - Suppression de height: 100dvh (déclenchait resize à chaque
     apparition/disparition de la barre nav iOS, causant pertes WebGL)
   - width/height retirés de .zone-content-unity (inset: 0 suffit
     quand position est fixed)
   ========================= */

/* =========================
   OVERRIDE BODY OVERFLOW
   Unity WebGL exige overflow: auto sur body.
   zone-core.css met overflow-x: hidden → on écrase ici.

/* =========================
   ZONE UNITY — CONTENEUR PRINCIPAL

   Position toujours fixed, quelle que soit l'orientation.
   On évite ainsi le changement de stacking context au passage
   paysage ↔ portrait, qui provoquait une perte du contexte WebGL
   et un rechargement de la scène Unity sur iPad/iPhone.

   IMPORTANT : avec position: fixed + inset: 0, le bloc couvre déjà
   exactement le viewport. Les propriétés width/height sont retirées
   car 100vw / 100dvh y seraient redondantes — et 100dvh est
   dangereux : sa valeur change quand la barre de navigation iOS
   apparaît/disparaît, ce qui génère des événements resize parasites
   pouvant provoquer une perte de contexte WebGL.
