# Auto-deploy SkateSpots to Netlify when the published origin/main changes.
#
# Driven by the systemd user timer `skatespots-deploy.timer`. It is SAFE by
# construction: it only ever deploys committed code, and it never touches a
# dirty working tree.
#
# One-time setup (see AGENTS.md):
# netlify login
# netlify link # choose the existing SkateSpots site
#
# Manual run / debug:
# scripts/auto-deploy.sh
# journalctl --user -u skatespots-deploy -n 50
