Show HN: [npm] Recreation of YouTube's "ambient glow" effect

I’ve been a bit obsessed with YouTube’s subtle “ambient glow”, that soft, blurred backdrop behind the video player. YouTube creates it by blurring a desaturated thumbnail from their video spritesheet, but I always felt it could be done without relying on that extra service.

After a bunch of failed attempts, I finally landed on an approach I really like and packaged it up as my first npm release.

It’s a pretty niche project, but if you’re into visuals, CSS filters, or performance-friendly UI polish, I’d love your thoughts and ideas.
