/* PA-07 tracker: design system.
 *
 * A data page, not a marketing page: dark text on a light ground, one accent
 * per party, and no colour that does not mean something. The rule the whole
 * palette rests on is that COLOUR ENCODES PARTY and LINE STYLE ENCODES VENUE.
 * Polymarket and Kalshi both quote the same Democratic probability, so giving
 * them separate hues would imply they measure different things; solid versus
 * dashed says "same quantity, different book". It also survives being printed
 * in grey and read by someone who cannot separate blue from red.
 *
 * Everything is sized in rem off a 16px root so the page respects the reader's
 * own text size, and every layout switch is a min-width query rather than a
 * max-width one, so the phone layout is the base case and not the fallback.
