/*
 * One stylesheet, no build step.
 *
 * The marketing pages and the application share it because they share a
 * vocabulary — a panel, a badge, a table, a field — and two stylesheets that
 * drift apart is how a product ends up looking like two products.
 *
 * Colour is load-bearing here in a way it is not on most sites: pass, warning
 * and block are the three things a reviewer reads first. So each carries a
 * symbol as well as a hue, and none of them is the only signal for anything.
