   SystemMatch Monitor — console

   The token set below is lifted verbatim from the pre-sales site's
   css/site.css, so the two products read as one. Only the monitoring-specific
   components are new.

   The four semantic colours map straight onto the four states, which is a
   fortunate accident of the original palette:

       teal   → OK          amber → WARNING
       red    → CRITICAL    faint → UNKNOWN

   This is an operations console: dark ground, dense information, and every
   colour carrying meaning. Nothing is coloured for decoration, because in a
   room where someone is looking for the one red row, a decorative red is a
   fault in the product.
