   § 05 AI 名片 · the scroll-driven phone
   Left: four step blocks in the normal flow (the paper docks live here).
   Right: one phone, pinned with position: sticky. The phone is authored at a logical
   360 px width; its screen height (--screen-h) and scale (--fit) depend on the viewport
   only, never on what it shows. Every phase is stacked in one grid cell and changes by
   opacity / transform, so playing the demo never changes a layout box.
