name: Sync → HF Space (env server)

# Pushes the repo to the env-server HF Space on every commit to main.
# The Space rebuilds its Docker image automatically, which downloads
# scenarios from HF Hub and restarts the env server.
#
# Required GitHub secrets:
#   HF_TOKEN      - HuggingFace write token (Settings → Secrets → Actions)
#   HF_USERNAME   - your HuggingFace username
#   ENV_SPACE_NAME - name of your env-server Space (e.g. "ci-triage-env")
#
# The training Space is NOT auto-synced here (rebuilding mid-training would
# kill a running job). Manually push to it when you want to update.
