/*
 * AnyiNavi design system. Written for AnyiNavi; no third-party CSS.
 *
 * One set of components for light and dark: every colour comes from the
 * tokens below; html[data-theme="light" | "dark"] is set before the first
 * paint (inc/setup.php). The accent colour comes from the Customizer
 * (--accent) and everything accent-coloured is derived from it, so any
 * choice keeps readable contrast.
 *
 * Breakpoints (same as the legacy column settings): sm 576, md 768,
 * lg 992, xl 1200, xxl 1400.
