Build me a JavaScript animation library for the modern web that can animate pretty much anything, like CSS, SVG, canvas, colors, strings, motion paths, and plain objects.

I want the core to be fast, reliable, and framework agnostic, with clean support for sequencing, easing, and precise control over values changing over time. Please include scroll based animations with a ScrollTrigger style feature, plus responsive animation handling, and make sure it works smoothly in all major browsers.

It should be easy to use from npm or a CDN, with a simple main import and optional plugins users can register when they need them. If you need to check current docs or browser details online, go ahead. Also include TypeScript types and a few practical examples so it’s easy to understand how to use it in a real project.
