"""fal.ai Hunyuan3D v2 image->GLB for the two TRELLIS glass rejects (glass-case, bus-shelter).

Paid — John-authorized (ROUND5 decision #4; account topped up). ~14-17c/gen, <=2 attempts each,
every gen logged to AUDIT.md by the caller. Uses the owner's FAL_KEY configured in MODELBEAST
settings (never hardcoded here) via MODELBEAST's own settings loader — the same env-injection the
server does. MUST run with MODELBEAST's server venv python (it has fal_client):

    MBPY=~/Documents/MODELBEAST/.venv/bin/python
    $MBPY pipeline/gen_props_fal.py CONCEPT.png OUT.glb

Prints `FAL_OK <glb> ~$0.16` on success (cost is the caller's to record), `FAL_ERR ...` on failure.
