 * what goes in it. Custom properties are declared on :root (read everywhere)
 * or on the same element that reads them (.fs-badge--XXX, .fs-bar__over).
 * Phone first: the page is laid out for 360px and widened with min-width
 * queries. Motion only runs under prefers-reduced-motion: no-preference.
