SimoHypers/limusic ? reverse-engineered prompt

Build me a native desktop YouTube Music app that feels fast and modern, not like a browser wrapper. I want it to let me sign in to my YouTube Music account, search and browse songs, albums, artists, playlists, and the home feed, then play music with clean ad free audio, gapless playback, queue support, and loudness normalization. It should handle my library too, like liked songs and playlists, and let me like tracks, add them to playlists, create or rename playlists, and subscribe to artists.

Please also include synced lyrics in a side panel, a mini player, support for local music files, Last.fm scrobbling, Discord rich presence, system tray controls, media key support, and a way to keep the app looking nice with themes and fonts. If anything needs current docs or tricky setup details, look them up online as needed.
