# upgrade.sh — pull the latest manage-server image and restart.
#
# Takes a pre-upgrade pg_dump backup. DB schema migrations run automatically
# on container startup — no manual migration step required.
#
# Usage:
#   sudo bash upgrade.sh                # latest from ghcr.io
#   sudo bash upgrade.sh --image TAG    # pin a specific image tag
#   sudo bash upgrade.sh --port PORT    # change the web UI host port
