Build me a browser extension that makes streaming video look better and tells me what it is doing.

It should trick streaming sites into sending the best quality my device can handle, then enhance the video right on the page with a sharpen and upscale pass so soft or compressed streams look clearer. I want a small toolbar popup that shows the current stream quality and explains when I am not getting the best version, plus a simple way to turn the enhancement on and off.

Also add a few quick modes for the image, like balanced, sharp, anime, and custom, and let me compare the original and enhanced video with a split view. If it makes sense, include keyboard shortcuts for toggling the tool and showing the on screen readout. Keep it focused on watching videos in the browser, no extra settings screens or complicated setup. If you need to check current extension APIs or browser docs online, go ahead.
