"""
The QUIC MNP listener is off unless the operator turns it on.

No shipping client speaks QUIC (browser and desktop use WebRTC; the hub-less
`group://` sidecar is unbuilt), so a node that started it by default would only
be exposing a UDP port. `daemon.py` gates `QuicChunkServer` on
`self._config.node.quic_enabled`; these follow the value down the config path.
