 - **Web**: Fixed detached/form sheet autopresent animation, scrollable content, footer click, and grabber drag interactions. ([#684](https://github.com/lodev09/react-native-true-sheet/pull/684) by [@lodev09](https://github.com/lodev09))

 ### ⚠️ Breaking
 
 - Renamed `pageSizing: boolean` to `presentation: 'page' | 'form'` (default `'page'`). `presentation='form'` is absolute and ignores `maxContentWidth`. Migration: `pageSizing={true}` → `presentation='page'` (default); `pageSizing={false}` → `presentation='form'`.
