   KUTAY OS — Music app ("Studio Radio")
   A Spotify playlist library: browse public/personal playlists, add one by
   URL, listen in an embedded player. Kept as its own dark "listening room"
   regardless of the OS light/dark theme — like the Terminal, this page's
   mood is deliberately constant (the original never gave it a light-theme
   override either), not a token-system oversight.
