"""One-shot Hugging Face Space deployment for asos-tools-py.

Usage:
    set HF_TOKEN=hf_xxx   (Windows)
    export HF_TOKEN=hf_xxx   (macOS/Linux)
    python deploy/hf_deploy.py [--space-name NAME] [--private]

Reads the token from the HF_TOKEN env var only. Never logs or commits it.

Release #2 architecture: the HF Space runs a multi-process Docker container
(nginx + streamlit + uvicorn under supervisord), so this script uploads:

  * asos_tools/         Python package (includes api.py + icons.py)
  * assets/             4K transparent image assets
  * .streamlit/         Streamlit theme config
  * deploy/nginx.conf   supervisord + nginx configs referenced by Dockerfile
  * deploy/supervisord.conf
  * deploy/entrypoint.sh
  * app.py, owl_logo.png, requirements.txt, Dockerfile
  * deploy/huggingface_README.md  -> uploaded as README.md (Space frontmatter)

Intentionally excluded from the Space:
  * deploy/hf_deploy.py     (this script itself)
  * deploy/build_*.py       (one-time dev tooling)
  * .github/                (GitHub Actions, not needed inside the container)
  * tests/, images/, CLAUDE.md, CHANGELOG, etc.
