Fix: 36pt = 36px, not 48px

• Changed .monologue's font-size to `@font-size-base * 1.5` (36px) instead of `* 2` (48px).
	» I had accidentally changed my browser's font-size.  Whoops.
	» Discovered this when trying to figure out why the text was wrapping on some long lines (e.g. “… ancient Greeks…”) when there's plenty of room in the mockup.
