   JSU City — Aleph Bet v3 "Jerusalem stone at golden hour"
   Visual-only layer for the Aleph Bet course + vowel labs.
   Every rule is scoped to #alephCourseOverlay.aleph-v3 (the class is
   added by js/aleph-v3.js) so removing that one class restores v2.
   Requires the tokens defined in css/ui-v3.css.
