/*
  Networking 7 — supplemental stylesheet
  Layered on top of peters-course.css (must be linked first).

  Networking 7's pages were originally built by several different chat
  sessions and never converged on one set of class names the way the
  AOS/OSF pages did. Rather than rewrite the markup of every page, this
  file re-points the class names that already exist in the Networking 7
  HTML at the same colours, type and shapes peters-course.css defines —
  so the page looks identical to an AOS/OSF page without every div
  needing to be renamed by hand. New rules only; nothing here overrides
  peters-course.css's own classes.
