        <h4 style="color:var(--orange);">&#x1F4A1; Best Practices</h4>
        <ul>
          <li>Use <strong>both</strong> X-Frame-Options and CSP for maximum compatibility.</li>
          <li>Set headers on <strong>all pages</strong>, including error pages.</li>
          <li>Prefer <code style="font-family:'Space Mono',monospace;font-size:.75rem;background:var(--ink);color:var(--yellow);padding:1px 4px;border-radius:3px;">DENY</code> unless you need same-origin embedding.</li>
          <li>Test regularly — security regressions happen!</li>
