Build me a cross platform desktop app for streaming and downloading movies, TV shows, and anime, with a clean modern interface and no ads or tracking.

I want users to be able to search for titles, browse trending and popular stuff, open a title page with posters, details, and episodes, then stream it right inside the app. For movies and TV I want metadata from TMDB, and for anime I want it to switch to AniList automatically. Also add subtitle support, a downloads section, and a simple library so people can keep track of what they watched and what they want to watch next.

Make it feel fast and polished, with a few customization options in settings, and support for both streaming and downloading from the sources the app uses. If you need to look up current docs online while building it, go ahead.
