/* =====================================================================
   Uibig Tech Dashboard

   Everything above the "ADDITIONS" rule is lifted unchanged from the
   approved mockup (uibig-dashboard-mockup.html). Tokens, typography,
   layout, component classes and the LED status wall are as designed.

   Below that rule is only what a live application needs and a static
   mockup did not: the login screen, dialogs, forms, toasts, empty and
   loading states. It reuses the same tokens throughout.
