/* =========================================================
   header.css
   The floating nav pill.

   The lockup is wide (roughly 1.6:1, compass + goose + wordmark), so it is
   ABSOLUTELY positioned and centred: its height must not drive the height of
   the bar. The pill reserves room for it with its own padding. This is the
   Wildridge lesson, where a 100px badge in normal flow sized the whole bar.

   Because the mark is wide rather than a compact badge, the links run out of
   room earlier than they would on a circular logo, so the drawer takes over
   at 1100px instead of the usual 900.
