Build me a self hosted YouTube downloader web app with a clean Material Design look and dark mode.

It should let me paste a video link, grab the media, show a simple dashboard of downloads and their status, and let me manage my library from the browser. I want it to feel polished and easy to use, not like a command line tool. Please make it work as a full app with a frontend and backend, and include support for running it locally or with Docker so it’s easy to deploy on my own server.

If it makes sense, add a settings area for basic configuration, a way to expose an API for automation, and make sure the app can handle larger libraries without slowing down too much. Look up current docs online if you need to, and keep the experience straightforward for someone who just wants to run it and start downloading.
