Yeah, that's some of what I meant by the old "light" being "special." Old "light" had very little CSS, so it never actually SET a font size at all! The new "light" does.

We'll need to think a bit about how to deal with "light." It might end up being "visually light" instead of "raw-ass html light" going forward, or we might re-implement some special behavior for it. Kind of depends on a lot of things.
