/* ==========================================================================
   Ember case-study layout, integrated into the projects master/detail pane.
   Used by projects-ember.html only.

   Structure follows noemititarenco.com/projects/ember/: a centred ~820px
   column, mono meta rows, a large display headline, a framed hero screenshot,
   then prose with section headings and a feature list.

   Typography and palette come from the portfolio: Cormorant Garamond for the
   article, mono for labels and controls, graphite ground and cream ink.
