16 generated assets plus the grass billboard atlas and the four debris models
copied verbatim from the 3D-STORE library (copies rule, §0). All meter-scale,
Y-up, and far under the 15k tri budget — garden_bed is heaviest at 2,580.
Regeneration is byte-deterministic: two consecutive runs produce identical
files, so re-running the factory causes no churn.

One script regenerates every nature/hardware asset in PLAN3D §5-E, following
the house idiom from 3D-STORE/racks_to_glb.py: reset per asset, build under a
root empty at the origin, join by group, stamp props, export Y-up GLB.
Groups are joined per sway-unit rather than per-asset, so trees keep trunk and
canopy_* as separate nodes for Lane A to animate. Paths resolve from __file__
instead of a hardcoded home dir, since the library lives elsewhere on this box.
Verification re-imports each exported GLB from disk and asserts dims, tri
budget, and node-name survival, then renders it against the 1.7 m ref capsule.
Checking the file rather than the in-memory scene is what makes it a real test.
