Optimize Astro GSAP Performance

My Astro-powered homepage relies on GSAP timelines and a lightweight Three.js scene, yet it drops frames, blocks user input, and takes far too long to settle after first paint. I need a specialist who can dive into the code, profile what’s really happening in the render loop, and bring the frame rate back to a rock-solid 60 fps without sacrificing the visual flair.

Here’s what I expect:
• A concise audit pinpointing the bottlenecks in my current GSAP and Three.js setup (physics, shaders, texture sizes, timeline overlaps, event listeners, etc.).
• Refactoring or replacing any heavy logic so the initial load is snappy and subsequent interactions feel instant.
• Measurable wins—Core Web Vitals and a smooth scroll/interaction experience—as proof that the fixes work in production.

Tooling such as Chrome DevTools, Lighthouse, WebGL inspector, and whatever GSAP plugins you prefer are all fair game as long as the final code stays within the Astro framework. Once the homepage is silky smooth, I’ll extend the same approach to the rest of the site.

Drop a short note explaining your relevant GSAP/Three.js performance projects, and we can get started right away.
