Quick Patterns
// Spotlight Hero
<div className="relative h-screen bg-black">
<Spotlight className="absolute top-0 left-0" fill="white" />
<div className="relative z-10">
<h1>Content</h1>
</div>
</div>
// 3D Card
<CardContainer>
<CardBody className="bg-gray-50 rounded-xl p-6">
<CardItem translateZ="50">Title</CardItem>
<CardItem translateZ="100"><img src="..." /></CardItem>
</CardBody>
</CardContainer>
// Flip Words
<h1>Build <FlipWords words={["faster", "better", "smarter"]} /> apps</h1>
SSR & Hydration
// ALL components require 'use client'
'use client'
// Heavy components: dynamic import
import dynamic from 'next/dynamic'
const Globe = dynamic(() => import('@/components/ui/globe'), { ssr: false })
// Hydration fix pattern
const [mounted, setMounted] = useState(false)
useEffect(() => setMounted(true), [])
if (!mounted) return null
Performance Tips
// Reduce particles on mobile
const count = isMobile ? 20 : 100
// Respect reduced motion
const prefersReducedMotion = window.matchMedia('(prefers-reduced-motion: reduce)').matches
