/* ============================================================
   SUPPORT-PAGE.CSS
   The 3 sections unique to support.php: a dark jump-nav hero, a
   3-card contact-channel grid (light), and an FAQ accordion
   (light, checker bg). The closing section reuses final-cta's
   classes from sections-v2.css. Depends on the same root tokens
   in style.css.
