[feat] Show some kind of animation while element is being re-written with AI

Perhaps a gradient overlay, or something fancy that prevents the user from adjusting the element while it is being processed with AI. It'd be a great UX if there was a visual indicator that the element that was selected was in-process of being improved. Open to ideas! Also could do something fancy like .svg dust with .svg filters.

Oooh cool I like that idea. We have to think about whether we want the user to interact with anything on the page while the AI is "thinking" because it could override the changes it's supposed to make.
