/*
  Plumbline, designed as one piece. Loaded after styles.css (which still owns the replay's behaviour), so this file is the whole look.
  Remove the <link> to it, or run ..\plumbline-web-v1-backup\ROLLBACK.ps1, to return to the original site.

  Identity: a survey sheet whose dots are the nodes of the graph; a plumb bob as the one physical object; brass for the bob,
  red only for "exposed". Type and detail follow Apple's playbook: one workhorse face with optical sizing, tracking that
  depends on size, springs for anything touchable, materials that carry hierarchy, and gentler paths for reduced motion,
  reduced transparency and more contrast.
