   four sides, and the mark grew with the logo. At full size that is ~69px, so
   28px would now crowd the lockup against the hero edge. The vw term tracks
   the requirement down through the range where the logo is shrinking to fit. */

   links are something. flex-wrap means that on narrow screens the nav drops
   to its own row and the gap becomes vertical separation instead. */

   show), and min(..., 100%) lets it shrink to fit instead of forcing a
   horizontal scrollbar. height:auto keeps the ratio intact while it does.
