23fpsz/SpotiDuck-Releases ? reverse-engineered prompt

Build me an Android app called SpotiDuck that wraps the Spotify web player in a fast WebView, but feels like a real music app on Android.

It should let me sign in, play music in the background, show media controls on the lock screen, and keep working when I switch apps. Add built in ad blocking, a home screen widget, landscape support, and Android Auto support if possible. The app should have a clean Spotify style interface, with screens like home, library, and a full screen player.

Make sure it handles the common WebView issues as well as it can, like login problems, blank screens, and playback stopping because of battery optimization. Include a simple settings area for compatibility options, and set it up so users can download the latest APK from releases. If you need to check current Android or WebView docs, look them up online.
