/* ═══ SHARED ONBOARDING OVERLAY ═══
   Same visual pattern as BM Voice's onboarding (first tool to have
   one) — reused here for BM Words, BM Career, and Better Me so a
   student sees a consistent style across every tool. Relies on the
   --navy/--white/--muted/--serif/--sans variables already provided by
   css/design-tokens.css, which every ai-lab page already links. */

/* ═══ ONBOARDING MINI-ANIMATIONS ═══
   Small self-contained "scenes" (56x56px) replacing the plain numbered
   circle — each mimics the actual action of its step (tap a card,
   speak, listen, type, save, upload, scan, score, check in, tick a
   checklist, grow a chart). Deliberately NOT tied to any real element
   on the page (no coordinates, no selectors into the live UI) — this
   is Option B from the earlier design discussion: less flashy than a
   full product-tour-style spotlight, but immune to breaking whenever
   the real page's layout changes later. */
