/*
 * api-dr-runner dashboard — design tokens and components.
 *
 * Colour comes from the validated data-viz palette (see docs/dashboard.md). Two rules here
 * are load-bearing for the product's honesty model, not for taste:
 *
 *  1. INCONCLUSIVE and NEVER-RUN have NO status hue. They are rendered in neutral ink on a
 *     hatched / dotted chip, because they mean "we did not observe this", which is a
 *     different thing from a bad result and must not read as a shade of failure.
 *  2. Every status is carried by glyph + word as well as colour. #fab219 (warning) and
 *     #ec835a (serious) measure only 13.6 normal-vision deltaE apart, so hue alone cannot
 *     be trusted to separate them — and roughly 1 in 12 men cannot use hue here at all.
