/* IELTS admin panel — self-hosted styles.
 *
 * ❗ THIS FILE EXISTS SO THE PANEL CAN SHIP A STRICT, ENFORCING CSP.
 *   Every other browser surface on this box had to compromise: WeightPath's
 *   admin CSP is still Report-Only because it pulls Tailwind/Alpine/Chart.js
 *   from CDNs and Alpine needs 'unsafe-eval'; Combined's is enforcing but needs
 *   'unsafe-inline' for 48 inline handlers. Keeping all CSS and JS in real
 *   files, with no inline <style>/<script> and no external origin, is what lets
 *   the vhost send:
 *       default-src 'self'; script-src 'self'; style-src 'self'; ...
 *   with no unsafe-* at all.
 *   ⇒ DO NOT add an inline style attribute, an inline <style> block, or a CDN
 *     <link> to any admin view. It will be blocked by the browser, and the fix
 *     is not to weaken the header.
