Self-contained host-network Avahi container publishes the service names over mDNS so .local works zero-config for guests (macOS/Linux native, Windows needs Bonjour). Toggle with ENABLE_MDNS=true + BASE_DOMAIN=*.local; build-stack layers docker-compose.avahi.yml in and builds the image during --prep. mDNS can't serve the air-gap upstream spoofs (non-.local) — those still need real DNS.
