   Mark Up (pages/markup.html) as a scribe's desk: a ruled sheet on wood to
   write on, sample texts, a brass seal to mark it up; the result a leaf of
   vellum with the chosen word's catalogue card in the margin. Words keep
   V4's meanings - one analysis, several (green), none (red) - in scribal
   pigments: ink, verdigris, rubric. Tokens come from catalogue.css.
