"""MoCapAnything V2 — HuggingFace Space (ZeroGPU) thin shell.

Clones the GitHub repo and runs its unified demo app (demo/app.py). That app auto-
detects the ZeroGPU environment (`import spaces`), loads models on CPU at import,
downloads weights + demo data from the Hub, lazy-fetches character meshes per species,
and serves the interactive demo — the SAME code as the local demo, so the two never
drift apart.

Code: https://github.com/phongdaot/MocapAnything
