Performance-focused YouTube Chat enhancement script.

Features:

Reflow Stabilization: Apply CSS containment to chat containers to prevent browser layout lag during fast-moving streams.

Ad-Slot Nuke: Uses a MutationObserver to intercept and remove ytd-ad-slot-renderer and engagement panel ads as they are added to the DOM.

Performance: Neutralizes ad-related scripts by toggling them to text/plain before removal.

High-contrast Cyber-Cyan timestamps for better readability in dark mode.

Console Sanitization: Suppresses common YouTube telemetry noise and violations in the browser console for a cleaner forensic view.
