/*
  mygeeg design system — foundations (cream white & blue edition)
  ----------------------------------
  Tokens, reset, typography, forms, buttons, alerts, auth screens.
  Components live in app.css. Light + dark themes via [data-theme] (set by theme.js),
  falling back to the visitor's OS preference.

  Legacy token names (--ink, --gold, --signal, --text-hi …) are kept as aliases so that
  older inline styles in templates keep working.
