ShaderGradientBackground used 3 full-screen Three.js WebGL canvases
with a blur(150px) CSS filter, crashing Lighthouse and causing severe
lag in Chrome. BackgroundBlobs also had 7 elements with blur(100-120px)
and per-frame mouse spring tracking compounding the issue.
- Remove ShaderGradientBackground from layout (WebGL not needed for a blur effect)
- Reduce BackgroundBlobs blur from 100-120px to 60px
- Remove mouse tracking spring animations from BackgroundBlobs
- Reduce to 4 blobs (remove 3 least visible)
