pub const LOSSY_WARNING: &str = "Could not switch this session to the PKCE client: \
CD-quality tracks will stream as AAC instead of FLAC";Expand description
Warned (logged by the Authenticator, printed by login) when a token
of the device-flow client is used because the PKCE client failed (AC19).
It names no cause: at login it covers any failure, outages included.
