/* =============================================================================
   VoteSecure — recruitment site
   -----------------------------------------------------------------------------
   Colour is testimony, not decoration.
     Seal red  (--seal)     marks only what is unsolved / open.
     Green     (--verified) marks only what verifiably runs.
   Every other surface is paper, ink and pencil. If a red or green mark is not
   carrying that meaning, it does not belong on the page.

   Red and green are never the ONLY signal for a state: the OPEN stamp is a
   bordered box containing the word "OPEN"; the "runs" list uses a check glyph
   and the word. Both parse with all colour removed.
