/* ==========================================================
   Project Core — stylesheet

   This is an internal work-tracking tool. It is read many times
   a day by people scanning for what changed, so it is built for
   density and legibility rather than impact: tight vertical
   rhythm, tabular figures so dates and numbers align down a
   column, and colour reserved almost entirely for status, where
   it carries information.

   Colour is the one place there is any boldness. Everything
   else stays quiet.
