   RISE — Warm Archival Paper, Overhead Swaying Leaf Shadows & Watercolor Eye
   - Leaf shadows sit ABOVE the eye (z-index: 25, mix-blend-mode: multiply)
     so tree leaves naturally cast real shadows across both the paper and the eye!
   - Smooth, speckle-free Watercolor Wash mask on the eye (no sandy pixel noise!)
