/*
  peakops.css
  The film stays pinned. The four steps on the right fill a vertical rule as
  the story scrolls. The 12-week timeline follows that story in the document,
  so it is not on screen until the last step has completed.

  The rule is decorative. Each step's number, title, and sentence carry the
  meaning (1.4.1 Use of Color). Reduced motion and narrow screens show every
  step at full strength without the pinned scroll (1.4.10, 2.3.3).
