  YSD Education Institute demonstration site.

  Editorial direction: near-white paper, deep ink type, vermilion accents and
  soft mint panels on a 12-column grid. Headings use a humanist sans stack that
  covers Traditional and Simplified Chinese with local system fonts only, so no
  third-party font host is contacted at runtime.
