/* =========================================================
   SYLLABUS PAGE — page-specific only.
   Loaded solely by syllabus.php via $pageExtraCss.

   Deliberately a different structure from entrance-examination.css:
   a sticky sidebar (jump nav + contact) alongside a flat, borderless,
   zebra-striped item list per level — no enclosing bordered panel,
   no pill level-badge, no numbered chip (a small doc icon instead).
