/* ---------- Walkthrough: tour, guides, welcome and the getting-started checklist ----------
   Engine styles first (js/walkthrough.js), then VectoR's own pieces (js/onboarding.js).
   Colours come from index.html's :root tokens; nothing here introduces a new one apart from the
   scrims, which are the ink colour at an opacity. --wt-z sits above the sheet (80), the step
   popover (70), the save bar (60) and toasts (50). */
