maxdorninger/MediaManager ? reverse-engineered prompt

Build me a self hosted media library manager for TV shows and movies, with a clean modern interface that makes it easy to manage, discover, and automate my collection in one place.

I want it to feel like a simpler replacement for the messy media stack people usually stitch together, with support for signing in through OAuth or OIDC, and metadata lookup from TVDB and TMDB. It should be easy to run with Docker, with a straightforward setup flow, a config file, and sensible defaults so I can get it online quickly.

Please make the main experience polished and easy to use, with pages for browsing my library, checking what is missing, and managing items without a lot of technical clutter. If you need current implementation details, look up the latest docs online and follow the project style.
