  # Host networking: nginx listens on 50002 directly on the host IP.
  # Declared so the APP GATE can see this port. Host networking means Podman
  # publishes nothing (quadlet skips PublishPort in host mode), so `bind:` here
  # is a statement of where the container's own nginx listens — 127.0.0.1 —
  # not a publish instruction. Without this declaration the gate had no idea
  # the port existed: it was neither protected nor listed as unprotected, and
  # served the Electrs screen unauthenticated on every interface.
