[Unit]
# Freezmo — production release (self-hosted study app).
#
# Runs the "current" release symlink: scripts/deploy.sh atomically flips it and
# restarts this unit, so production only ever runs a pushed, verified commit.
# Layout: ~/freezmo-prod/{releases/<name>,current -> releases/<name>,shared}
#   current/server/server.js   standalone Next server (built by the deploy)
#   current/server/.env.local  -> shared/env.local
#   current/server/.freezmo    -> shared/freezmo   (sync/, push/)
#
# Install (per user, no root needed):
#   mkdir -p ~/.config/systemd/user
#   cp ~/freezmo/deploy/freezmo.service ~/.config/systemd/user/
#   systemctl --user daemon-reload
#   systemctl --user enable --now freezmo.service
#   loginctl enable-linger "$USER"     # start at boot without logging in
# Logs:  journalctl --user -u freezmo -f
