 ### 🐛 Bug Fixes
 - **Mobile Header Brand**: `MagicStarterAppLayout` mobile topbar now honors `navigationTheme.brandBuilder`, so custom brand widgets render consistently across breakpoints when provided ([#65](https://github.com/fluttersdk/magic_starter/issues/65))
+- **Page Header Title Truncation**: `MagicStarterPageHeaderTheme` defaults now use `line-clamp-2` instead of `truncate` for `titleClassName` and `subtitleClassName`, so long titles wrap to a second line on narrow viewports (e.g. iPhone-width screens) instead of clipping to "AI sett..." ([#67](https://github.com/fluttersdk/magic_starter/issues/67))
