// and rejects "1"/"0" silently; if it can't parse our DIDL it regenerates
// its own with generic class object.item, no title, and the URL query
// string as the displayed name (logcat 2026-06-04 confirmed). Match the
// SoCo convention which the firmware definitely accepts.
// Sonos requires (a) the rinconnetworks namespace declared on
// <DIDL-Lite> even if we don't use Rincon elements directly, and
// (b) a <desc id="cdudn"> element identifying the URI as an
// external (non-Sonos-library) source. Without those, Sonos
// discards our metadata content and regenerates its own with
// class=object.item and the URL query string as the title
// (logcat 2026-06-04 confirmed). Match SoCo's pattern.
