/* Help modal restructure (Instructions / Walkthrough / FAQ / Hotkeys) and the
   guided tour overlay. Loaded last so it wins over earlier help styling.

   The tour deliberately never runs while a <dialog> is open: an element shown
   with showModal() paints in the browser's top layer, above all body content
   regardless of z-index, so a body-level overlay could never cover it. The
   launch button closes the help dialog first. See "VPXS UI Gotchas". */
