/* ============================================================
   MDJLABS — ATELIER · « Creator Studio » (scène PL.3, isolée)
   ------------------------------------------------------------
   UNE seule scène (#pl-studio), épinglée, scrubée, réversible.
   Le studio est UNE entité continue : un tableau de bord qui se
   construit et travaille au fil du scroll (piloté par --tp via
   atelier-studio.js) — jamais 4 captures qui se remplacent. Les
   10 entités (6 éléments + 4 jalons) traversent les 4 états :
   clips de montage → jalons sur le parcours → nœuds du graphe →
   nœuds audités par l'IA. Le noyau (coquille studio) persiste.
   Réutilise la coquille .plx-* de prolearn-scroll + le chrome
   d'atelier .atx-* de atelier-atome. CE fichier = studio + scène.
