Detailed Description

Output-selection popup: route audio to the Jack or a Bluetooth speaker.

A small centered box (drawn over black) reached from Now Playing (UP). Three rows: the wired Jack, a Bluetooth speaker, and a shortcut into the Bluetooth settings screen. The Bluetooth row is dimmed and inert while no device is connected. Selecting an output calls the single routing entry point player_set_output(), which re-routes a live stream and powers the unused path down itself – so this screen only expresses the choice, it does not touch hardware.

A Bluetooth switch is refused only when no speaker is connected (the row is dimmed); an un-acked speaker volume does not refuse it — the player defers the stream until the ack (never blast) and the switch call still succeeds.
