/* ============================================================
   GENE HEW v13 - the van in 3D (2026-09-24, entry 2026-09-25)
   The entry is the van as a scale model on a paper plinth, standing on the van photo: it turns,
   drags round, and a tap swaps the photo for the live model in the same frame. Pill controls
   match the site's buttons; pins are the six spec lines. Additive layer, loaded last.
