"""PROCITY Lane D — interior figure-scale gate (Round 10 regression guard).

Guards the R9 blocker: interior rig figures came out ~2x too tall (keeper head at 3.83 m in a
3.4 m room) because rigs.js `buildFigure` normalised by the head bone's world Y in BIND POSE —
which is head-above-hips (the skeleton origin), ~half the standing height — instead of the
feet->crown span. Fixed in R10 (normalise by `headY - minY`).

This gate boots the real game, enters a sample of open shops, spawns browser rigs at every browse
point (occupancy is 0 right after boot, so we inject it to exercise the browse spawn path
deterministically), and asserts for EVERY spawned interior figure:
    1.4 m <= STATURE (crown - foot) <= 2.0 m        (human-sized — platform-independent)
    crown(head-bone world Y) < room dims.H          (never clips the ceiling — its own line)
    |feet(min-bone world Y)| < 0.05 m               (planted on the floor)
Exits non-zero if any figure fails, so tools/qa.sh --strict fails a giant before it can ship.

[Lane F R13 — debt #6] The human-size check measures STATURE (feet→crown span), not the raw world
crown, so it stays correct the day a figure stands on a platform (a keeper on a 0.3 m riser is not a
giant). This is the same measure smoke_gigs uses for the band on Lane C's stage deck, now ported into
the shared gate; the world-crown "never clips the ceiling" assert is kept as its own separate line
(that is the real R10 failure mode). For floor figures foot≈0 ⇒ stature≈crown ⇒ fully backward-compatible.

Run:  tools/.venv/bin/python tools/qa/interior_scale_check.py [--seed N]
Setup: the same Playwright venv as tools/soak.py / tools/flags_check.py.
Needs Lane B's window.DBG hook (?dbg=1) + window.PROCITY.interiorMode (Lane C/F).
