/* ─────────────────────────────────────────────────────────────────────────
   Public site — Modelação 3D showcase
   Mirrors the structural rhythm of the Web Design page (hero + sticky
   filter pills + zigzag case studies) but the centre piece is an A-Frame
   3D viewer stage instead of a desktop+mobile mockup cluster. The stage
   itself stays flat (no 3D rotation on the wrapper) so the viewer's own
   look-controls keep mapping mouse coordinates correctly.
