Part of #2
The scope in crates/records/src/groove.rs of atmosynth-audio-engine grows to cover modules, web tiles, plyr.fm tracks and the service auth rooms use, so an account consents once. The site's editor asks for extras as they are used; Groove does not. An account already signed in is asked again the next time it needs what it was not granted, and is told why in the fewest words that do.
