New component/KeyboardAwareScreen.tsx encapsulates the standard
KeyboardAvoidingView pattern for full-screen forms:
- iOS behavior="padding", Android no-op (adjustResize covers it)
- scrollable prop: ScrollView with keyboardShouldPersistTaps="handled"
- non-scrollable: TouchableWithoutFeedback+View for tap-to-dismiss
- headerOffset prop for screens owning their own header padding
Migrated to KeyboardAwareScreen: signin, signup, forgot-password,
confirm-otp (SafeAreaView-wrapped, no headerOffset needed) and
profile/edit (KAV wrapper only, explicit ScrollView retained).
