I noticed another thing I have to override in Pure, that seems opinionated.
I can't think of a reason for this.

.pure-g [class *="pure-u"] {
font-family: sans-serif;
}
Suppose I specifically choose a font-family for my site with
body {
font-family: fontOfMyChoice;
}
anywhere I use grids, I'll see 'san-serif' instead of my font.
