   The look is the TNG *Technical Manual*, not LCARS: drafting stock, blue
   annotation, a serif set at reading size. Deliberately the opposite of the
   LCARS theme that is coming later, so the theme switch is a transformation
   rather than a recolour.

   The one loud element is the designation in the rail — s954e12, s1.073x10e8,
   s247e47. The absurd numbers are the best thing in the archive and they are
   set at a size that says so. Everything around them is quiet.
