   --------------------------------------------------------------------------
   Tokens + canonical class patterns shared across the ProEstimate web app.
   Pages opt in by adding the `.pe-surface` class to a layout root. Pages
   without `.pe-surface` keep their existing styling.

   Tokens are exposed at :root so any descendant can read them; class
   patterns are scoped to `.pe-surface` so unmigrated pages aren't affected.
