# ServerAlive* keep the session alive across long-running
# `docker compose recreate` steps where the remote command
# produces no stdout for >60s. Without keepalive the
# cloudflared tunnel (and the OpenSSH client) drop the
# session and exit 255 even though the host-side deploy
# script keeps running — observed on the PR #111 merge
# (run 26419696840). 30s interval × 8 retries = 4 min of
# network silence tolerated before the session is killed.
