ShuShuzinhuu/SpotiFLAC-Mobile — reverse-engineered prompt

Build me a clean mobile app for Android and iPhone that lets people paste a song, album, or playlist link and download the tracks in true FLAC to their device. I want it to feel simple and polished, with a search bar, download queue, progress states, artwork, and a settings area for storage access and download preferences. It should support built in music sources like Tidal, Qobuz, and Deezer, and also let users add more sources such as Amazon Music through an extension system.

Please include a Store screen where the user can enter an extension repository URL, browse available extensions, install them with one tap, or manually import a .spotiflac ext file from settings. There should also be a way to change provider priority so if one source fails it can try another. Make sure playlist links work, failed downloads show a helpful reason, and the app is ready for localization. If anything is unclear, check the current docs and README online and finish the app in a working state.
