NanKillBro/glassy-music-nankill — reverse-engineered prompt

Build me a custom desktop music player app that feels like a heavily styled glassy version of YouTube Music. I want the main focus to be the visual vibe, with a polished glassmorphism look, custom shaders and effects, and an opinionated default theme that looks great right away, but still lets people switch themes in settings if they want.

Please include synced lyrics support with Better Lyrics style theming, built in ad blocking, and a nonstop playback fix so it does not stop with the usual continue watching prompt. It should feel like a personalized fork with some extra flavor and UI tweaks, not a generic skin.

Make it work as a packaged desktop app for Windows, Linux, and Mac, and keep in mind that the visuals are a bit heavy so it should be aimed at decent modern hardware. If possible, make the Windows build easy with a simple script, and set up the normal source build flow for the other platforms too. Look up current docs online if you need to.
