d0x-dev/AirFlix ? reverse-engineered prompt

Build me a polished Android streaming app called AirFlix that lets people browse movies and TV shows, play them smoothly, and download them for offline viewing. I want a clean Material 3 style interface, with watchlists, viewing history, subtitles, multiple audio options, and support for external players or download tools. It should also let users add their own content sources so the app can pull from different providers.

Make it feel fast and modern, with a nice home screen, search, details pages, and a great video player experience. Keep it open source friendly, and make sure the app can be built and run easily from the repo. If anything is unclear, check the latest docs online and keep the implementation simple, stable, and ready for Android use.
