 /// Check if UPnP is available by attempting SSDP discovery.

+/// The socket is a blocking `std::net::UdpSocket`, and on a network with no
+/// UPnP gateway — the normal case right after a node moves — the recv runs
+/// out its full read timeout. Inline on the runtime that parked a tokio
+/// worker for those 3s on every call, the same failure shape (smaller blast
+/// radius) as the OpenWrt SSH connect that stalled the API on framework-pt.
+/// Keep it on the blocking pool.
