/* ══════════════════════════════════════════════════════════════
   FIRST-TIME ONBOARDING TOUR
   A small coachmark sequence — see src/ui/onboarding.js. Deliberately
   simpler than the confirm/alert/prompt modals in modals.css: no dimmed
   full-page backdrop punched with a hole, just a highlight ring positioned
   over the current target plus a tooltip card, so the rest of the app stays
   visible (if not interactive) throughout the tour.
