Build me a YouTube app for Android TV and set top boxes that feels easy to use with a remote, not like a phone app stretched onto a TV.

It should let people browse and watch videos comfortably on a big screen, support 4K playback, and work without Google Services. I want a clean TV style home screen, search, playback controls, and a login flow so users can sign in and keep their content up to date. Please make it localized for multiple languages, and include a search keyboard that works well with a TV remote.

On first launch, show a simple setup screen where the user can pick the device and playback mode, choose a maximum resolution and codec, and save those choices for future launches. If possible, make the app support automatic updates too. Keep it polished for TV use, support common remotes, and make the whole thing feel like a real living room YouTube client rather than a desktop web app.
