# Loopback-only by default: ttyd here is writable (-W) and unauthenticated, so
# binding all interfaces hands a shell as this user to any network peer. This
# mirrors the containerized default (TTYD_BIND=127.0.0.1 in
# src/deploy/entrypoint.sh). To expose it beyond localhost, front it with the
# authenticated dashboard proxy, or change -i and add a credential
# (-c user:pass) via a drop-in override.
