/* ============================================
   FuseIoT — Digital Twin Stage (seção About)
   Palco escuro "turno da noite" com cena Three.js, HUD, painel cream
   (.iris-demo) e tour guiado. Interiores construídos por js/digital-twin/.

   IMPORTANTE: o GSAP (js/animations.js) é dono do transform de .dt-stage
   (parallax ±3%) e o base.css é dono da entrada de .about__twin — este
   arquivo NUNCA seta transform/animation no .dt-stage em si (filhos podem).

   Z-layers internas do palco:
   canvas 1 · vignette 2 · fade 4 · statusbar 5 · hud/label 6 · painel 7 ·
   guide 8 · gate 9
