- Create large 500% conical gradient with pastel color cycle
- Position gradient off-screen (-200% top/left) for smooth rotation
- Add 8s linear infinite rotation animation for fast testing
- Use ::before pseudo-element to avoid repainting main content
- Cycle through various pastel shades (pink, purple, blue, green, yellow, orange)
- Performance-optimized: only transforms, no gradient repainting
