   Direction: "Field notes". Warm paper white, black ink, and a colour per
   beat. The palette is not decoration: each clip carries its subject's colour
   on the rail dot, the meta line and the card edge, so the timeline reads as
   a spectrum of what she covers rather than a uniform list.

   Shadows are used only for elevation on things you can interact with, and
   are tinted green rather than grey so they sit in the paper instead of on it.
