/* ==========================================================================
   Iguazu Noticias — Primary navigation

   Progressive enhancement: without JavaScript the burger never appears and the
   menu stays laid out, so the site is navigable on a phone with scripts off.
   site-nav.js adds .has-js to the header, which is what switches the small
   screen layout over to a collapsible panel.
