   USE-CASE TEMPLATE — reusable sub-page for case studies.
   Structure: fixed canvas background (hero gradient + cross grid)
   → parallax decor layer (design / AI nodes, data-depth)
   → Figma-frame sections (.frame) joined by prototype connectors
   → footer.
   To make a new case: copy this file, swap the copy / images inside
   each .frame, keep the .slot / .frame / .el structure so the
   connector + parallax JS keeps working.
