Open folders and scroll position stay put when the list reloads.
A favorite with a missing folder goes back to Uncategorized.

Seller email and social links show again after Fab's layout changes, without duplicates.
Description videos use a real YouTube thumbnail, a play button, and a highlighted active thumb.
Clicking a carousel image closes the playing video.

Popup:
Tailwind is compiled CSS instead of a runtime script. Lighter popup, better Firefox support.
