### ⚡ KEY DEFENSE ENGINES

🚫 **Aggressive Popup, Popunder & Fullscreen Hijack Defuser**
- Traps unauthorized `window.open` calls directly at `document_start`.
- Neutralizes synthetic link click exploits, popunders, and hidden anchor triggers.
- Stops deceptive fullscreen hijack attempts (`requestFullscreen` lockouts) used by phishing websites.
- Discrete floating toast notification with 1-click "Allow Once" or "Whitelist Site" options.

🔀 **Anti-Redirect, Tab-Under & History Trapping Shield**
- Neutralizes timer-based redirects (`location.replace`, `location.assign`, meta refresh).
- Stops inactive background tabs from quietly redirecting to scam landings or fake download traps.
- **History Trapping Defense**: Defuses rapid `history.pushState` and `replaceState` loops that freeze your browser's "Back" button while preserving normal SPA navigation (YouTube, Gmail, Twitter).

🎬 **Video Pre-Roll & VAST Defuser (Fix Error Code: 224003)**
- Intercepts VAST video ad requests and returns standard clean empty VAST XML.
- Permanently fixes the dreaded "This video file cannot be played (Error Code: 224003)" on JWPlayer and HTML5 players.
- Sanitizes video player configurations and automatically skips pre-roll countdown timers.

🕵️ **Anti-Tracking, Fingerprint Spoofing & Deep Shadow DOM Scanner**
- Blocks cross-site ad networks, analytics beacons (Google, Meta, TikTok, Criteo), and session heatmaps.
- **Deep Shadow DOM Scanner**: Recursively traverses open shadow roots (`element.shadowRoot`) to eliminate disguised trackers and embedded ads.
- Spoofs Canvas 2D and AudioContext APIs with imperceptible, deterministic micro-noise to defeat cross-site device fingerprinting.
- WebRTC IP Leak Defense prevents local and public IP disclosures over non-proxied connections.
- Automatically strips tracking query parameters (`utm_*`, `fbclid`, `gclid`, `mc_cid`, etc.) from clicked links.

⚡ **Prominent Element Zapper (Alt+Shift+Z)**
- Point, laser-target, and vaporize any annoying floating banner, video overlay, or newsletter modal with 1 click.
- Includes depth adjustment slider to expand or narrow container targeting.
- Permanently remembers and applies cosmetic CSS hiding rules across visits.

🍪 **Cookie Consent Auto-Dismissal & Scroll Recovery**
- Automatically detects and dismisses intrusive GDPR/CCPA cookie walls without accepting tracking.
- **Reactive Scroll Unlocker**: Continuously clears forced `overflow: hidden` and modal lockouts on news sites.
- Neutralizes adblock detector traps (`canRunAds`) to prevent page breakage.

🎨 **StreamGrabber Design System & Dual Tone Theme**
- Switch instantly between Light Tone (☀️) and Dark Tone (🌙).
- Unified, clean typography and responsive components.
