# Free Hugging Face Spaces pause after a stretch of no traffic. This cron pings the public Space URL
# so the demo stays warm and loads instantly for anyone you share it with. Set the Space URL as a
# repo VARIABLE (Settings -> Secrets and variables -> Actions -> Variables): name SPACE_URL, value
# e.g. https://<your-username>-amana.hf.space  (the direct app URL, not the /spaces/ page).
# If SPACE_URL is unset the job no-ops, so this is safe to merge before the Space exists.
