Build me a clean Android TV launcher app like Arc Launcher, with a modern home screen that feels better than the stock TV launcher.

I want a simple, fast interface for TV boxes and Fire TV sticks, with app categories, easy app sorting, a watch next row, and a settings area that’s easy to reach with a remote. Please include a small data usage widget for WiFi usage, a shortcut to WiFi settings from the network icon, and a screensaver that is friendly to OLED screens so it avoids burn in.

It should support custom wallpapers, including day and night switching, a pitch black option, and even video backgrounds if possible. Make the focus movement smooth and obvious, with clear highlighting and no weird bouncing around. Keep it open source friendly, lightweight, and polished.
