/* =========================================================================
   mon-cms pixel theme — shared design tokens
   -------------------------------------------------------------------------
   Served from cms/server/static so both ContestWebServer and AdminWebServer
   load the same file:  static_url("static", "pixel", "pixel-tokens.css").
   The ranking server keeps its own copy under cmsranking/static/pixel/.

   This file defines ONLY tokens, fonts and a handful of primitives that every
   surface shares. Per-application overrides live in
     contest/static/cws_pixel.css   (contestant site, on top of Bootstrap 2)
     admin/static/aws_pixel.css     (organiser site, on top of aws_style.css)
     cmsranking/static/Ranking.css   (scoreboard; has its own copy of this file)

   Reference look: warm off-white paper with a faint dotted grid, chunky
   pixel display type in near-black, a dark-green block cursor, monospace
   body text, square 1px-bordered controls with a hard offset shadow.
