Consider adding optional address filters to overlays.

This will allows us to restrict overlay styling to simulants at or parented by a specific address like how CSS is restricted to applying to named divs and their contents.

Would overlay update dynamically as they do in css?

I wonder if it might make sense to take some cues from CSS selector syntax or even just the much simpler XPath syntax.

Though if they update dynamically, the scope could become massive once animations and such are considered.

That's the intent, I believe. Tho I can't tell you for 100% sure since it's been a long time since I've thought about this.

Not sure if the xpath syntax is related since this is something the engine will do automatically, not involving the user in anyway.
