   HEADER MODIFIERS
   Add to the header Section (class "header"):
   .header--pill     menu sits inside a rounded pill
   .header--overlay  header floats over the hero on pages whose
                     first section is a .hero (other pages unchanged)
   --header-height is measured by a small script in functions.php.

   STICKY + SHRINK
   Add to the header Section (class "header"):

   .header--shrink  once scrolled: smaller padding and logo, a
                    background and a shadow. Use with --sticky.
   Both work with .header--pill and .header--overlay. A small
   script in functions.php adds .is-scrolled to #brx-header.
