Filters posts with videos using dynamic content detection, improved performance.
The filter now works not only on user profile pages (/user/*) but also on the main global posts search page (/posts).
A new, dedicated panel is added at the bottom-right of the screen.
The script now creates and displays small visual preview cards for the video posts it finds. These cards show a preview image or a small video player directly in the list.
Video previews in the generated cards are "lazy loaded". They only start downloading and playing when you scroll down and they become visible on your screen.
The UI panel can be collapsed (hidden) and expanded again to save space on the screen. The state is saved for your next visit.
