> Sure, we can sort-of reason about this stuff e.g. with a hierarchical css+html+js structure, but without a way to render that I challenge you to be able to simply diff that information. Seeing "bold" or "blue" seems simple enough, as long as you also know to which elements it applies and in what layout. So, suddenly you can't reasonably diff the css file without also difficulty the html.

We’re in complete agreement. But you can do this, you just need to provide a “renderer” and a schema that describes how your tree structure should merge or conflict. If you want to test out a weird version control for structured data, my email is in my bio.
