/* --------------------------------------------------------------------------
   The turn, told simply — You → Nura → the specialists → Answer
   (views/story.js, 2026-10-15)

   For an operator who is not technical: four steps that never grow wider,
   each specialist a card in its module's colour saying what it does now.
   What is working glows; Nura's light breathes while Nura thinks, and a card's
   icon while it looks at what it found. Under the answer, the line that
   opens to the diagram above names who worked on it.
