Barrel.css?

Working on a class-light CSS theme, would this be a good fit for inclusion? It can technically be used drop-in with OK results, but it does require a small number of simple classes for the best look.

Hacking together a quick test on the standard page looks OK if kind of dated, mostly becayse the framework expects that content goes in a .window class element for the nice background, as it's designed for apps, where you might have multiple separate windows within a main tag.
