   Phone Screenshots - Safari-Compatible Drop Shadow

   Safari has a bug where drop-shadow on a parent element renders against
   the bounding box instead of the alpha channel. The fix is to:
   1. Apply drop-shadow to the img element directly
   2. Remove hardware acceleration hints (translateZ, backface-visibility)
      from the parent that interfere with alpha compositing
   3. Use will-change: transform on the parent for smooth hover transitions
   4. Add micro-animation to force recomposite on page load
