/* Thousands x Bets stylesheet.

   Structure comes from hairline rules and a left locator margin rather than boxes, echoing the
   numbered rulebooks in the corpus. Serif (Source Serif 4) is for text a person wrote; mono
   (IBM Plex Mono) is for anything a machine emitted: scores, ids, enums, counts.

   Every text/background pair meets WCAG AA. --paper on --teal is only 2.84:1, so teal as a
   background always takes --ink text. */
