Punktfunk (native punktfunk/1) Low-latency game-streaming host over the native punktfunk/1 protocol (QUIC control plane). Opens the default QUIC control port plus mDNS for auto-discovery, and the mgmt/library REST API (HTTPS + mTLS; off-loopback it serves only read-only status/library to paired clients). The media data plane uses an ephemeral UDP port negotiated per session, not opened here.
