/* ==========================================================================
   Site header: the single header for every public page (templates/partials/site_header.html).
   Uses only .site-header* classes so rules in app.css / theme.css / home.css cannot leak in.
   Layout: three grid columns (brand | nav | actions); the outer columns are equal, so the
   navigation is always exactly centred. Below --sh-collapse the nav moves into a menu panel.
