   tutorial.css — the guided walkthrough layer (window.DemoTutorial).
   Namespace: .dt-*  ONLY. It never styles .dp-* (presentation) or
   .ds-* (shell), and it never touches the app's own classes.

   Everything derives from the app's tokens (css/styles.css), so light
   and dark follow the product with no theme block of my own. The one
   local alias set lives on .dt-root.
