* v3 ships two runtime-switchable tracking engines (HUD overlay, tap top third):
* opencv (default) — joint multi-marker board solve (solve-cv.js). All detected
* corners -> one solvePnP -> camera pose. Non-coplanar wall
* corners -> one solvePnP -> camera pose. A non-coplanar
* crest removes planar ambiguity outright.
* posit — the v2 per-marker POS-IT + fuseWorld path, kept intact for
* on-table A/B until the new engine is confirmed. Delete later.
