/*
  A4O MANUAL EDITING GUIDE
  ========================
  This file intentionally contains the easy-to-change settings and readable layout
  overrides. The original compressed design remains in styles.css.

  QUICK CHANGES:
  1. Change logo sizes in :root immediately below.
  2. Change graph box positions under "A4O FOUR-PILLAR GRAPH".
  3. Change testimonial appearance under "TESTIMONIAL CAROUSEL".
  4. After editing, increase the ?v= number beside custom.css in index.html so
     browsers download your new version instead of displaying a cached copy.
