Adds a density-field floor/wall profile audit along passages near mouths (0.125 m spacing; L23
terraced negative control detected) and a reusable 12-view passage capture set (80 deg FOV, eye
height, LOD0, skirts off, capped clip planes). The old blurry mouth shot was camera framing; the
L33 entry ledges were tile skirts. Owner world hashes unchanged; 24/24 passage rows, 30/30
determinism, 16/16 invariants; cost within noise.
