Sliver of body background showing under footer in Safari #9
Description
Caused by the fractional values generated in the Utopia variables.
Shows up at with a full height window on my 27-inch, 3840 x 2160 monitor, where changing reading-bg's padding-block from --space-500-600 (which here comes out to 35.944915771484375px) to 36px makes it go away.
Changing --space-400 from 19.1610164642334px to 19px also makes it go away.
So it's not one particular variable or value that's causing the bug. I believe it's that I'm using fractional values at all, and probably not helped by the high levels of precision in them.
