963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

Use Native Modals Over JS-Based Bottom Sheets
Use native <Modal> with presentationStyle="formSheet" or React Navigation
v7's native form sheet instead of JS-based bottom sheet libraries. Native modals
have built-in gestures, accessibility, and better performance. Rely on native UI
for low-level primitives.
Incorrect (JS-based bottom sheet):
import BottomSheet from 'custom-js-bottom-sheet';
function MyScreen() {
const sheetRef = useRef<BottomSheet>(null);
return (
<View style={{ flex: 1 }}>
<Button onPress={() => sheetRef.current?.expand()} title="Open" />
<BottomSheet ref={sheetRef} snapPoints={['50%', '90%']}>
<View>
<Text>Sheet content</Text>
</View>
</BottomSheet>
</View>
);
}
Correct (native Modal with formSheet):
import { Modal, View, Text, Button } from 'react-native';
function MyScreen() {
const [visible, setVisible] = useState(false);
return (
<View style={{ flex: 1 }}>
<Button onPress={() => setVisible(true)} title="Open" />
<Modal
visible={visible}
presentationStyle="formSheet"
animationType="slide"
onRequestClose={() => setVisible(false)}
>
<View>
<Text>Sheet content</Text>
</View>
</Modal>
</View>
);
}
Correct (React Navigation v7 native form sheet):
// In your navigator
<Stack.Screen
name="Details"
component={DetailsScreen}
options={{
presentation: 'formSheet',
sheetAllowedDetents: 'fitToContents',
}}
/>
Native modals provide swipe-to-dismiss, proper keyboard avoidance, and accessibility out of the box.
