/* Maxwell's point charges (research/maxwell-charges). f0.css tokens only.
   Equilibrium kind is never colour alone: 1-saddles are filled cyan dots (--mark-dig), 2-saddles are gold rings
   (--mark-bio); charges are ink discs. In the scoreboard the bound is a grey line with hollow squares, the best known
   counts are ink dots, and a red hairline ring (--hair) marks counts from this study. */
