/* ==========================================================================
   SMIJ THEME INTEGRATION BRIDGE
   Added by the SMIJ theme; not part of the Metro stylesheet above. This part
   wires that stylesheet to real OJS markup: the mobile nav toggle (the base
   styles assume Bootstrap's navbar-collapse JS, which isn't loaded here),
   the menu OJS renders via {load_menu}, the topbar login/register menu, the
   footer column grid (no Bootstrap grid loaded), and CSS-only skinning of a
   couple of native OJS templates (article list, issue heading) that this
   theme does not override, so an OJS update to those templates can't break
   the theme. Edit navy/gold in Website > Appearance > Theme, not here.
