   TeleTonicMD Patient Portal — foundation stylesheet
   Consumes brand-tokens.css (link it BEFORE this file). Provides the shell
   (header/nav/footer), component library (cards, buttons, inputs, chips,
   list rows), and the perceived-performance kit (skeletons, toasts, empty
   states). Every portal page (login, dashboard, visit, billing, intake,
   ai-assistant, signup, reset) migrates onto these classes.
