 * Primary navigation + candidate mega menu.

 * The inherited header stylesheet carries `.header nav { display: none }` and
 * `.header button { display: none }` - left over from the hidden Etch demo nav.
 * `.header--has-nav` opts this header back in without touching that rule, so
 * any page still using the old markup is unaffected.
