"""Deploy the current repository to a single HuggingFace Space.

Intended to be called from CI (see ``.github/workflows/deploy_spaces.yml``),
one invocation per matrix entry so that deployments run in parallel.

Environment variables:

* ``HF_TOKEN``    -- HuggingFace access token (required).
* ``HF_USERNAME`` -- HuggingFace username/organisation (required).
* ``SPACE_NAME``  -- Target Space name (required).
* ``SPACE_SDK``   -- Space SDK, defaults to ``streamlit``.
