   DERILA ERGO PILLOW — derila-ergopillow.us  (rebuild #2, new domain)
   Template : "cloud-zones" — airy, rounded, sky-blue/white layout
              built around the product's own 5 support-zone map
              (back wings, front wings, shoulder-arch release,
              central core, arm-support area), rendered as a soft
              hotspot-style diagram. Intentionally light/rounded/
              pastel, the structural and visual opposite of the
              navy, angular "sleep-lab" diagnostic template used for
              the first Derila build (deriilaergopillow.com) and all
              17 other templates used across prior builds.
