/* /syllabus/ hub: the ten parts of the notes, the books, and the full theory and practical syllabus.
   Three night stages: .ci-lotus (ten petals, one per part), .ci-shelf (five prescribed books),
   .ci-path (theory and practical as paths of dots that light while you scroll).
   Motion uses transform and opacity only; nothing animates until JS adds .is-live, and
   reduced motion drops every animation (style.css already drops transitions). */
