/**
 * Travelport Ticket Tracer admin — styles.
 *
 * Self-contained: system font stack, no external fonts/assets. Light theme,
 * dark slate sidebar, white content. Chart colors follow the dataviz method:
 * a single validated accent hue for the carrier bars (magnitude = length,
 * identity = the row label, so one hue is correct), status colors always
 * paired with a text label, values in ink — never in the series color.
