/**
 * Internal Global Message — front-end styles.
 *
 * Colours come from per-message custom properties printed inline by
 * Config\Css::build_for_message(), so this file stays static and cacheable.
 *
 * Bars and popups start hidden and are revealed by the script once it has read
 * the visitor's dismissal state. That avoids a dismissed bar flashing on screen
 * on every page load, which is the cost of keeping the HTML identical for
 * everyone so it stays safe to page-cache.
