-//! Backend-agnostic music renderer façade for PMOMusic.
-//!
-//! `MusicRenderer` wraps every supported backend (UPnP AV/DLNA, OpenHome,
-//! LinkPlay HTTP, Arylic TCP, Chromecast, and the hybrid UPnP + Arylic pairing) behind a
-//! single control surface. Higher layers in PMOMusic must only interact with
-//! renderers through this type so that transport, volume, and state queries
-//! stay backend-neutral.
