/* ==========================================================================
   moonsver — a spec sheet in blue

   The library implements a written standard, so the site is set like one:
   paper, hairline rules, a serif for figures and headlines, and mono for
   anything a reader might type. Colour comes from the four given blues only.

   Two motifs recur:
     · the offset sheet — a solid blue card under a translucent white one,
       the way two pages sit when they are stacked and nudged apart;
     · the straight edge — where a block has a rule down its left side, that
       side stays square and only the right corners are rounded, so the rule
       reads as "|" and never as "(".
   ========================================================================== */
