+/* =============================================================================
+   Typography
+
+   To achieve a pleasant vertical rhythm, we use Compass' Vertical Rhythm mixins
+   so that the line height of our base font becomes the basic unit of vertical
+   measurement. We use multiples of that unit to set the top and bottom margins
+   for our block level elements and to set the line heights of any fonts.
+   For more information, see http://24ways.org/2006/compose-to-a-vertical-rhythm
