"""Galaxy setup owner for Spotify Soloist, modeled on the Android Auto package flow.
|
||
|
||
The HTTP server must authenticate the caller before invoking this owner. The API key is write-only:
|
||
no method here returns it. Configuration that changes the running player (install, output, account)
|
||
uses the shared connectivity authority (Park or offroad); playback controls work in any road state.
