/* Dubai Health Authority, 2008 — the project story, second build.
   The rule taken from the artwork: three quarters and an open fourth. The manual says it itself: "An incomplete shape.
   DHA will complete the picture." So the words live in the open, lower-left quarter, the pictures take the other three,
   every change of ground arrives a quarter at a time with the open one last, and the mark only ever turns by quarters.
   Five chapters, each pinned, with a heading in normal flow between them.
   Two modes. Without JavaScript, with motion off or with reduced motion: a plain page, every beat with its pictures.
   With motion: scroll position alone decides every pose (scene.js sets --n, --q, --x on each beat). */
