/* ═══════════════════════════════════════════════════════════════════════════
   EXPLORATEUR 3D (Distribution Canada → Documents → Catalogue de pièces → R10) — la machine en 3D
   à gauche, le catalogue détaillé à droite (en dessous sur téléphone). Monté par
   wwwroot/js/explorateur-3d.js (et sa géométrie, modeles3d/<clé>.js) dans la page du modèle. La SCÈNE garde un fond clair dans les
   deux thèmes, légèrement assombri en sombre : une mini-pelle bleue se lit mal sur un fond noir.
   La sélection est ROUGE (--x3d-choix) : ni l'orange d'un moteur Kubota, ni le vert et jaune
   d'un concurrent.
