// ... etc
```

### GSAP Optimization
**Location:** `/src/pages/Services.tsx`

**Changes:**

- ✅ After: Dynamic import (loaded only when page renders)

**Implementation:**
```tsx
useLayoutEffect(() => {
  import('gsap').then(({ default: gsap }) => {
    import('gsap/ScrollTrigger').then(({ ScrollTrigger }) => {
      // GSAP code here
    });
  });
}, []);
```

### Bundle Optimization
**Location:** `/vite.config.ts`

**Improvements:**
- Manual chunk splitting for better caching:
  - `react-vendor`: React core libraries
  - `ui-vendor`: UI components (lucide-react, radix-ui)
  - `gsap-vendor`: Animation library
- Terser minification with console removal in production
- Optimized dependency pre-bundling
- GSAP excluded from initial deps optimization

### Build Configuration

**Key settings:**
```typescript
build: {
  rollupOptions: {
    output: {
      manualChunks: { /* vendor splitting */ }
    }
  },
  chunkSizeWarningLimit: 1000,
  minify: 'terser',
  terserOptions: {
    compress: {
      drop_console: mode === 'production',
      drop_debugger: mode === 'production',
    }
  }
