/* ------------------------------------------------------------------- scale
   One knob for the whole page. Every length below is in rem, so the root
   font size is what makes the site fill a big display instead of sitting
   small in the middle of it: 16px on a 1280px-wide viewport, ~19.5px at
   1080p, 23px at 1440p, 30px at 4K. Written in rem rather than px so a
   reader who runs a larger default font keeps it, scaled from there.

   Change this one line to make everything bigger or smaller at once. The
   pixel sprites step separately in --px at the bottom of the file, because
   pixel art can only be scaled by whole numbers without going mushy. */
