I had started to write a long e-mail about the three stages of CSS parsing
(tokenization, generic CSS, specific CSS1/2/3/SVG/Mobile/etc. parsing) and
how the rules for ignoring tokens only apply to the last stage, but David
Woolley stated it much better. A file that fails the generic CSS grammar
is simply not CSS and the spec says nothing about that case.

(Whether it should is a whole different debate.)
