Man, I would have appreciated it if someone had pointed that out to me
earlier.  I saw <ratio> used in MQ, but couldn't immediately find the
definition of it, and didn't find it in CSS3 Values, so I assumed that
when people were talking about it they were just referring to a
number.  Somehow I never looked at any of the examples in MQ either.

Um, never mind then?  We'll just use <ratio>.  Problem solved, discussion over.
