"""Validate web/assets/manifest.json — runs in Lane F's integration gate.

Checks: JSON parses; every referenced skin exists locally; every fitting/furniture GLB
exists locally (pipeline/_normalized) OR HEADs 200 on the depot; every thumb exists;
footprints & heights are sane; every registry shop type has >=2 facades.

    python3 pipeline/validate_manifest.py            # local + soft depot check
    python3 pipeline/validate_manifest.py --depot    # require GLBs live on the depot (post-publish)

Exit 0 = green, 1 = fail. Plain stdlib (no deps), so it runs anywhere.
