/* Reduced motion means reduced, not removed: the large moves go (the 3.5% image
   push, the full-height type rise), while the short fades, hovers and the pointer
   light stay — they are the difference between a page that answers and a page
   that sits there.

   The mode is a class on <html>, set before first paint from the visitor's
   stored choice or the operating system, and switchable in the footer. A media
   query alone would make the choice unreachable on a machine that has animations
   off; this way the setting is still the default, not a cage. */
