Dev-Zhao/skribbl.io-autodraw — reverse-engineered prompt

Build me a Chrome extension for skribbl.io that can automatically draw an image onto the game canvas.

I want to be able to open a small extension popup while playing, choose settings like draw mode and brush size, then drag and drop an image from my computer or from the web. The extension should resize the image to fit the skribbl.io drawing area, convert the image colors to the closest colors available in the game, and then draw it by simulating normal mouse drawing so it looks like a real player is drawing.

Please include at least a dots mode and a lines mode, and make sure the drawing process doesn’t freeze the page while it runs. It should work as an unpacked Chrome extension with a manifest, popup UI, background script if needed, and content scripts that interact with the game page. Keep the UI simple and clear, with basic styling and an icon.
