Use contentInsetAdjustmentBehavior for Safe Areas

Use contentInsetAdjustmentBehavior="automatic" on the root ScrollView instead of wrapping content in SafeAreaView or manual padding. This lets iOS handle safe area insets natively with proper scroll behavior.

Incorrect (SafeAreaView wrapper):

import { SafeAreaView, ScrollView, View, Text } from "react-native";

function MyScreen() {
  return (
    <SafeAreaView style={{ flex: 1 }}>
      <ScrollView>
        <View>
          <Text>Content</Text>
        </View>
      </ScrollView>
    </SafeAreaView>
  );
}

Incorrect (manual safe area padding):

import { ScrollView, View, Text } from "react-native";
import { useSafeAreaInsets } from "react-native-safe-area-context";

function MyScreen() {
  const insets = useSafeAreaInsets();

  return (
    <ScrollView contentContainerStyle={{ paddingTop: insets.top }}>
      <View>
        <Text>Content</Text>
      </View>
    </ScrollView>
  );
}

Correct (native content inset adjustment):

import { ScrollView, View, Text } from "react-native";

function MyScreen() {
  return (
    <ScrollView contentInsetAdjustmentBehavior="automatic">
      <View>
        <Text>Content</Text>
      </View>
    </ScrollView>
  );
}

The native approach handles dynamic safe areas (keyboard, toolbars) and allows content to scroll behind the status bar naturally.
