/**
 * Admin interface styles.
 *
 * Adapted from the plugin's design system (sbst-base, sbst-themes, sbst-modals) — the spacing scale,
 * colour choices and modal behaviour carry over. What has gone is sbst-overlay.css, which existed only
 * to hide WordPress admin chrome, and the per-screen files, which fought each other through unscoped
 * selectors.
 *
 * Everything is expressed against custom properties, and dark mode redefines only those.
