/*
  Plumbline.
  One bold first screen: a flag-red field, one question, and the real chain from a service down to the poisoned release,
  with a brass plumb bob hanging at the end. Everything after it is calm white paper with one card, the replay, where the
  detail lives. Red means "exposed" or "changed" and nothing else on the paper; the bob is the only brass.
  Springs for anything you can grab (js/spring.js), feedback on press, and gentler paths for reduced motion/transparency/contrast.
