name: Sync to Hugging Face Space

# Mirrors every push to main onto huggingface.co/spaces/f4b404/hermes
# so the Space rebuilds automatically. Free-tier HF Spaces don't expose
# the native "linked GitHub repository" feature, so we mirror by force-
# pushing the GitHub `main` branch to the Space's `main` branch.

# Required secret: HF_TOKEN — write-scope HF token from
