K3vinb5/unyo-app ? reverse-engineered prompt

Build me a simple desktop app for watching anime and reading manga with a clean, polished UI and no ads.

I want it to work on Windows, Mac, and Linux, and to sync automatically with AniList so my progress, watch history, and reading status stay up to date. It should let me browse shows and manga, open a title, play episodes or read chapters, and keep things easy to use. A nice modern design and smooth animations would be great.

If possible, include support for extension based content sources so new anime and manga providers can be added later, and make sure the app feels fast and reliable. If you need to look up current docs online for anything, go ahead.
