  # Bridge unified Go binary (cmd/bridge). Mainnet equivalent of the
  # bridge-go service in compose.testnet.yml and the Deployment in
  # k8s/bridge-deployment.yaml — same image, same env contract, same
  # mainnet chain set (networks.mainnet.yaml mirrors the k8s ConfigMap).
  #
  # Build locally before `docker compose up bridge-go`:
  #   docker build -f cmd/bridge/Dockerfile -t ghcr.io/luxfi/bridge:dev .
  # Then export BRIDGE_TAG=dev. For production, pin to a released tag
  # (e.g. BRIDGE_TAG=v1.2.3) rather than :latest so a registry retag
  # can't roll the running stack out from under you.
  #
  # Runs alongside bridge-server + bridge-ui during the §13.6 cutover
  # soak. Once the Go binary handles real traffic without regressions,
  # DNS at bridge.lux.network repoints to this service and the legacy
  # bridge-server + bridge-ui can be retired.
