## 🚀 Performance Improvements

### 1. Image Optimization (Cloudflare Workers Compatible)

**Important Note:**
Next.js `<Image>` component is **NOT compatible** with Cloudflare Workers runtime because it requires Node.js APIs that aren't available in the Workers environment.

**What Changed:**
- Used native `<img>` tags with `loading="lazy"` attribute
- Native browser lazy loading for below-the-fold images
- Kept `images.unoptimized: true` in `next.config.mjs`
- Background images for hero section (CSS-based)

**Benefits:**
- Native lazy loading (supported by all modern browsers)
- No runtime JavaScript overhead
- Cloudflare Workers compatible
- Fast initial page load

**Alternative for Advanced Optimization:**
For WebP/AVIF conversion and advanced image optimization on Cloudflare:
- Use [Cloudflare Images](https://www.cloudflare.com/products/cloudflare-images/) service
- Use [Cloudflare Transform API](https://developers.cloudflare.com/images/transform-images/)
- Pre-optimize images before uploading to R2

**Files Modified:**
- `next.config.mjs`
- `components/hero-section.tsx`
- `components/artists-section.tsx`

```javascript
images: {
  // Must be unoptimized for Cloudflare Workers compatibility
  unoptimized: true,
}
```

### 2. Hero Section Image Optimization

**What Changed:**
- Uses CSS `background-image` for hero background
- Optimized for Cloudflare Workers compatibility
- No JavaScript overhead for image loading

**Benefits:**
- Fast initial render
- Works in Cloudflare Workers runtime
- Browser-native rendering
- No hydration issues

**Files Modified:**
- `components/hero-section.tsx`

**Implementation:**
```tsx
<div
  className="absolute inset-0 bg-cover bg-center bg-no-repeat"
  style={{ backgroundImage: "url(/united-logo-full.jpg)" }}
  aria-hidden="true"
/>
```

**Note:** For production, consider pre-optimizing the hero image to WebP/AVIF format using tools like:
- [Squoosh](https://squoosh.app/)

- Sharp
- Cloudflare Image Resizing API

<img
  src={artist.workImages?.[0]}
  alt={`${artist.name} tattoo work`}
  className="w-full h-full object-cover"
  loading="lazy"
/>
