  version: 1.0.0
  description: |
    Archipelago-native HTTP frontend for LND. Runs nginx inside a
    container and serves static assets. LND connection info is fetched
    via an absolute URL that the host nginx routes to the archipelago
    backend on 127.0.0.1:5678, so no upstream auth is baked in.

  # Host networking: the container's nginx listens on 18083 directly (see
  # docker/lnd-ui/nginx.conf), because it has to proxy the archipelago backend
  # on 127.0.0.1:5678 same-origin — a bridge container cannot reach that, and
  # the cross-origin fallback broke the app on http-only nodes. `ports:` is
  # intentionally empty because host networking bypasses port mapping, exactly
  # as in apps/bitcoin-ui/manifest.yml.
  #
  # This previously declared `bridge` with 18083:80, which publishes the host
  # port to a container port where nothing listens. scripts/container-specs.sh
  # carried the identical mistake and was fixed alongside this; recreating from
  # it on a test node left :18083 refusing connections.
  # 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 LND screen unauthenticated on every interface.

      # strips it and every data call 401s while the page shell renders.
