/* =========================================================================
   Tutorials — the tenant viewer (#tutorialsScreen) and the super-admin
   authoring pane (#lobbyPaneTutorials).

   Same contract as maintenance.css, dataHub.css and landingShowcase.css:
   this sheet defines NO colours of its own. Every value is a var() from
   app.css's :root, so dark mode needs zero overrides here, and every offset
   uses logical properties (margin-inline, inset-inline-*) so Arabic and
   Kurdish mirror on their own.
