 * because the Content-Security-Policy is a flat `font-src 'self'` (see config/security.php) — a
 * Google Fonts URL would simply be blocked.
 *
 * `unicode-range` keeps a Turkish or Russian visitor from downloading subsets they cannot read.
 * Arabic is deliberately absent: it falls through to the platform's Naskh face, listed in
