name: Sync Hugging Face Space

# Publishes app.py + the algotrader package to a Hugging Face Space.
#
# Setup (one time):
#   1. Create the Space at https://huggingface.co/new-space with SDK "Gradio".
#   2. Add repository secret HF_TOKEN — a write token from
#      https://huggingface.co/settings/tokens
#   3. Add repository variable HF_SPACE_ID, e.g. "your-username/backtest-reality-check".
#
# Without those set the job is skipped, so forks and PRs are unaffected.
