/*
 * Harbour Institute of Vocational Education — public theme (SPEC-0087 §7).
 *
 * Institutional, quiet and accessible (WCAG 2.1 AA): system fonts only (no
 * web-font or CDN request, CSP SPEC-0006), 4.5:1 text contrast, visible focus,
 * and a two-level menu that opens on hover and on keyboard focus without
 * script. Block styles are namespaced `hive-` so this sheet can also load in
 * the visual editor's canvas without touching other sites' blocks; the page
 * chrome is scoped to `.hive-page`.
