                    <ul style="margin:0;padding-left:16px;">
                        <li><strong>🎯 Hide</strong> – Click any element to hide it (site‑wide or page‑only).</li>
                        <li><strong>❄️ Freeze</strong> – Block or allow navigation popups/redirects with fine‑grained rules.</li>
                        <li><strong>🔗 Link Extractor</strong> – Scan the page for all links, with media preview and download.</li>
                        <li><strong>⏩ Time Skipper</strong> – Jump forward 30 seconds on videos/audio and skip timers.</li>
                        <li><strong>👁️ Reveal</strong> – Unhide hidden/blurred elements (overlays, modals, etc.).</li>
                        <li><strong>📥 Media Downloader</strong> – Direct download of images, videos, and audio from extracted links.</li>
                        <li><strong>🛡️ Automatic Protection</strong> – Detects Cloudflare/challenge pages and temporarily disables features to avoid interference.</li>
                    </ul>

                    <p>The script automatically pauses all hiding/freezing/scroll‑override features when it detects a Cloudflare challenge, "Just a moment..." page, or other anti‑bot screens. This ensures that the script never interferes with the challenge process. Once the page loads normally, features resume instantly.</p>

                    <h4 style="font-size:10px;font-weight:700;color:#94a3b8;margin:8px 0 4px 0;">💾 Persistent Storage</h4>
                    <p>All rules, domains, freeze settings, and logs are saved locally (via GM_setValue or localStorage). Your customisations persist across browser restarts and site visits.</p>
