+## Import from Design System Folder
+
+Re-export dependencies from a design system folder. App code imports from there,
+not directly from packages. This enables global changes and easy refactoring.
+
+**Incorrect (imports directly from package):**
+
+```tsx
+import { View, Text } from 'react-native'
+import { Button } from '@ui/button'
+
+function Profile() {
+  return (
+    <View>
+      <Text>Hello</Text>
+      <Button>Save</Button>
+    </View>
+  )
+}
+```
+
+**Correct (imports from design system):**
+
+```tsx
+// components/view.tsx
+import { View as RNView } from 'react-native'
+
+// ideal: pick the props you will actually use to control implementation
+export function View(
+  props: Pick<React.ComponentProps<typeof RNView>, 'style' | 'children'>
+) {
+  return <RNView {...props} />
+}
+```
+
+```tsx
+// components/text.tsx
+export { Text } from 'react-native'
+```
+
+```tsx
+// components/button.tsx
+export { Button } from '@ui/button'
+```
+
+```tsx
+import { View } from '@/components/view'
+import { Text } from '@/components/text'
+import { Button } from '@/components/button'
+
+function Profile() {
+  return (
+    <View>
+      <Text>Hello</Text>
+      <Button>Save</Button>
+    </View>
+  )
+}
+```
+
+Start by simply re-exporting. Customize later without changing app code.
