3. **Main headline** - Slides up with gradient animation
4. **Subheadline** - Slides up (0.2s after headline)  
5. **CTA buttons** - Slide up with hover states (0.4s after headline)
6. **Stats section** - Animates in (0.6s after headline)
7. **Scroll indicator** - Appears last (2s delay)

### Continuous Animations
- **Parallax scrolling** - Background moves at different speeds
- **Gradient text** - Color shifts every 5 seconds
- **Particle system** - Responsive to mouse movement
- **Floating elements** - Gentle rotation and translation
- **Ambient lighting** - Subtle pulsing effects
