/* ─── Contextual Hint Tooltips ─────────────────────────────────
 *
 * One-shot hints for new users, shown the first time they land on a
 * surface or perform an action. Dismissed forever per hint, stored in
 * user-profile-store (localStorage + Supabase).
 *
 * Reuses the amber accent the demo guidance layer uses, so the visual
 * vocabulary is consistent: yellow/black bubble points at one thing.
 * Unlike the demo tour, hints never dim, never chain, and never block
 * interaction outside the bubble itself.
