/* ============================================================
   SXGuide — in-app guided tours, help drawer & demo mode
   ------------------------------------------------------------
   Dependency-free. Drives all four onboarding formats from one
   content schema: guided tour, autoplay demo, help drawer, and
   (via export) video narration scripts.

   All selectors are namespaced `.sxg-*` and mounted at a very
   high z-index so the module never collides with host styles.

   Brand: inherits the host surface's `--accent` etc. via CSS
   vars, falling back to the Caribbein kit (Ocean Teal).
