"""Deploy the IncidentCommander environment to a Hugging Face Space.

Uses the ``huggingface_hub`` Python API instead of ``git`` so this works on
Windows / macOS / Linux without requiring the git CLI.

Required env vars:

  HF_TOKEN       Hugging Face access token with `write` scope.
  SPACE_REPO_ID  e.g. ``alice/incident-commander``.

Optional:

  SPACE_PRIVATE  ``true`` to create a private Space (default: false).

Usage (PowerShell)::

    $env:HF_TOKEN = "hf_..."
    $env:SPACE_REPO_ID = "alice/incident-commander"
    python scripts/deploy_to_space.py

The script uploads the project root (excluding venv / build artifacts /
results) and HF's Space runner builds the Dockerfile automatically.
