   levels down set a grid track and panned a whole sibling site sideways —
   234px of overflow at 320px, a WCAG 1.4.10 failure that passed all 57 of
   that site's file checks, on the page its entire argument rested on.

   An enumerated list is a list someone has to remember to extend, so the
   base rules in base.css cap `.grid > *` and `.wrap`. These are the
