//! One-time PipeWire library initialization, shared by the video (portal) and audio capture
//! threads. `pw_init` must not be called concurrently from multiple threads on first use; both
//! capture paths connect to PipeWire at nearly the same moment (RTSP PLAY starts video + audio
//! together), so we serialize the init through a `Once`.
