I think this means that implementations must make a first pass at the 
whole cascade just to determine the page size, and then a second pass 
for everything else. Is this correct?

Unfortunately I don’t :/ I really see these two as contradicting.

WeasyPrint can choose any page size for the PDF, so the 'size' property 
is always used as is. Given this, the exact page size is known to 
authors, so media queries are maybe not as interesting.
