   4. ANIMATIONS - Fade-in effect for elements as they scroll into view
   ============================================================================

   HOW IT WORKS:
   - Add class "fade-in" to any element you want to animate
   - JavaScript adds "visible" class when element enters viewport
   - To disable animations, remove "fade-in" class from HTML elements

   ============================================================================ */

   6. HERO SECTION - Full-screen background image with text overlay
