/* ===========================================================================
   Mindspace - site header

   The header is sticky on every page: it is fixed to the top of the viewport
   and stays there while the page scrolls, condensing once the page has moved
   past 24px.

   Its height lives in --mind-nav-h so anchor targets can clear it. Pages that
   place content directly under the header should offset by that variable
   rather than repeating a magic number.
