+## Wrap Strings in Text Components
+
+Strings must be rendered inside `<Text>`. React Native crashes if a string is a
+direct child of `<View>`.
+
+**Incorrect (crashes):**
+
+```tsx
+import { View } from 'react-native'
+
+function Greeting({ name }: { name: string }) {
+  return <View>Hello, {name}!</View>
+}
+// Error: Text strings must be rendered within a <Text> component.
+```
+
+**Correct:**
+
+```tsx
+import { View, Text } from 'react-native'
+
+function Greeting({ name }: { name: string }) {
+  return (
+    <View>
+      <Text>Hello, {name}!</Text>
+    </View>
+  )
+}
+```
