DATA

```tsx
const chaptersData = [
  { name: "Age of Dinosaurs", image: "https://res.cloudinary.com/dsdxaxkiz/image/upload/v1779624247/01_udnber.png" },
  { name: "Fossils of Ancient Life", image: "https://res.cloudinary.com/dsdxaxkiz/image/upload/v1779624374/02_pmvxxl.png" },
  { name: "Reptiles of the Mesozoic", image: "https://res.cloudinary.com/dsdxaxkiz/image/upload/v1779624236/03_hcp3jc.png" },

  { name: "Prehistoric Giants", image: "https://res.cloudinary.com/dsdxaxkiz/image/upload/v1779624251/05_kz1tyu.png" }
];
```

STATE

```tsx
const [showVideo, setShowVideo] = useState(false);
const [activeChapter, setActiveChapter] = useState(2); // starts at "Reptiles of the Mesozoic"
const [isMobileMenuOpen, setIsMobileMenuOpen] = useState(false);
```

- `showVideo` flips to `true` after a 2800ms delay (setTimeout)
- `activeChapter` auto-cycles every 3500ms via setInterval, wrapping `(prev + 1) % 5`

ANIMATION VARIANTS

```tsx
const fadeUp = {
  initial: { opacity: 0, y: 20 },
  animate: { opacity: 1, y: 0 },
};

  initial: { y: 120, opacity: 0 },
  animate: { 
    y: 0, 
    opacity: 1,

SandTransitionImage COMPONENT

A custom component that creates a sand/particle dissolve effect using SVG filters:

```tsx
function SandTransitionImage({ src, alt, className }) {
  // Uses usePresence() from motion/react for AnimatePresence awareness
  // Unique filterId per instance via useRef
  // requestAnimationFrame loop over 900ms
  // Easing: entering = quartic ease-out (1 - Math.pow(1-t, 4)), exiting = cubic (Math.pow(t, 3))
  // SVG filter chain:
  //   1. feTurbulence: fractalNoise, baseFrequency 1.8, numOctaves 4
  //   2. feDisplacementMap: scale up to 150 based on progress
  //   3. feOffset: dy up to -80 (enter) or 120 (exit), dx up to -30/+30
  //   4. feGaussianBlur: up to 6px
  //   5. feColorMatrix: opacity fades (1 - progress * 1.2)
  // Image has crossOrigin="anonymous" and referrerPolicy="no-referrer"
}
```

KEY DESIGN DETAILS

- Color palette: `#fcfcfc` (off-white bg), `#111` / `#1a1a1a` (near-black), `#0a0a0a` (dark section bg). Gray scale via Tailwind: `gray-300` through `gray-800`.
- No purple/indigo anywhere. Strictly monochrome black/white/gray.
- Typography hierarchy: Large display headings (3.5-5rem), mono labels (10-11px), body text (13-14px).
- Spacing: 8px base system throughout.
- Transitions: Most hover transitions 300-700ms. Button slide effect uses `cubic-bezier(0.16, 1, 0.3, 1)`. Letter animations use same cubic bezier.
- The page is entirely a single `App.tsx` component plus the `SandTransitionImage` helper function in the same file.
