/* ==========================================================================
   Beyond Semantics
   --------------------------------------------------------------------------
   Palette comes from the logo artwork: #F52C50 sets the word BEYOND and
   #FE7664 sets SEMANTICS. The gradient between them is the site's one
   decorative device, used on the headline, the section numbers, the rules
   and the bullets, and nowhere else.

   Layout is a two column editorial rail: a narrow left column carrying the
   section number and label, a wide right column carrying the content.
