tbh, this started as a connection of two disparate ideas ("hey, this thing looks like this other thing"), and then just kind of explores it in different directions.

I think the conclusion (which I may not have made clear enough) is less like "These are limitations of modern CSS which ought to be fixed" and more "Maybe a CSS-like syntax could be added to a Datalog-like system and that would be helpful for making it more accessible to more engineers, navigating tree-shaped data, etc"

thanks for the feedback, anyway!
