• There are no unit tests covering the new canPlay.spotify logic. Adding tests for valid and invalid Spotify URLs will ensure correct matching behavior.

[nitpick] Consider anchoring the Spotify URL regex (e.g. using end-of-string or query parameter anchors) to align with other MATCH_URL patterns and prevent unintended partial matches.
