"""
One-shot deploy of the cleaned ImmunoOrg 2.0 repo to a fresh HF Space.

Reads token from the HF_TOKEN env var (or D:\\scaler-r2\\.hf_token if env
is missing), creates the Space if it doesn't exist, sets the
TRAINING_SECRET space secret, and uploads the whole repo as a single
commit using ``HfApi.upload_folder``.

Usage::

    python scripts/deploy_to_hf_space.py \\
        --repo-id hirann/immunoorg-v3 \\
        --training-secret auto      # or "skip" or a literal value
