Very good job, I love the minimal flat design.

Unfortunately, since it doesn't use any css preprocessor, it is impossible to create a semantic stylesheet. Now-days I would not consider any css framework that doesn't let me separate the presentation layer from the markup.

I realize this is meant to be a very lightweight framework, but in order to be usable it has to have the possibility to be extended easily without spawning classes everywhere.

Oh snap. Good point... but it really isn't that hard to just create a .less sheet, copy the styles into it and then compile that with your overrides and new classes. I have built a responsive template boilerplate with LESS on top of the html5 boilerplate using this method. Really not an issue to just add the CSS compiler or pre-processor of your choice. I do think it could be would be a viable core option for the Pure solution to offer a CSS interpreter option.
