AppTypography class

A ThemeExtension that exposes the design system's typography scale.

Provides all 15 Material TextTheme roles as individual TextStyle fields, registered in ThemeData.extensions for both light and dark themes — matching Spacing and CornerRadius's pattern.

Uses two typefaces across all roles:

  • Playfair Display — display, headline, and title roles.
  • Nunito — label and body roles.

Access via ThemeData using the ThemeExtras.appTypography extension, or pass toTextTheme to ThemeData.textTheme when constructing the app theme.

Do not instantiate this class directly in widget code. Always read it through Theme.of(context) (or context.theme) so that theme overrides and lerp animations are respected.
