# uninstall.sh — Remove the RemSound UDP relay and its auto-updater cleanly.
#
# Run with sudo:
#   sudo ./uninstall.sh
#
# Stops and disables both the relay and the updater timer, removes their
# scripts and unit files, and removes the /etc/remsound-relay/ state dir
# (version file + rollback backups). Leaves log files in place — rename or
# delete them yourself if you don't want them kept. Does NOT touch your
# router port-forward — that's separate.
