Anders Kaseorg 64b78ad992 styles: Use range context queries to eliminate *_max variables. ...

On a high-DPI display or with a non-default zoom level, the browser
viewport may have a width strictly between md_max = 767px and md_min =
768px.  Use only the *_min bounds for consistency.

This requires queries with strict inequalities to express upper
bounds (width < md_min).  Fortunately, that functionality is provided
by range context queries.  Unfortunately, those are not supported in
all browsers.  Fortunately, we can compile them away using
postcss-media-minmax.  Unfortunately, postcss-media-minmax currently
subtracts 1px for strict inequalities anyway to work around a Safari
rounding bug.  Fortunately, 0.02px should be sufficient for that, so I
submitted a PR:
