      <h2>How It Works</h2>
      <p>Each card has a <code>--depth</code> CSS variable that controls its position in 3D space. GSAP animates:</p>
      <ul>
        <li><strong>Transform:</strong> scaleZ, translateZ for depth positioning</li>
        <li><strong>Opacity:</strong> Cards closer to viewer are more opaque</li>
        <li><strong>Blur:</strong> Optional blur increases with distance (atmospheric perspective)</li>
        <li><strong>Delay:</strong> Each card stagger is calculated from its depth value</li>
      </ul>

      <h3>Technique Stack</h3>
      <p>This uses CSS 3D transforms with <code>perspective</code> container, GSAP for entrance choreography, and ScrollTrigger for scroll-based reveal. Hover states add interactivity.</p>
