AppTypography class

A semantic typography contract for the application.

AppTypography represents fully resolved text styles that are consumed directly by UI widgets. All styles exposed here are expected to be theme-aware and stable for the lifetime of the active ThemeData.

This class intentionally exposes only semantic variants. Mechanical differences such as font size, weight, or color composition must be resolved during theme construction, not in widgets.
