Every React Native 36,878 screen is built from a handful of core components: View is the box, Text holds all characters, TextInput is the editable field, ScrollView reaches content taller than the screen, and KeyboardAvoidingView keeps the keyboard off the field being typed in. Each becomes a real platform view, laid out by the Yoga flexbox engine and mounted by the Fabric renderer (JSI, Fabric, TurboModules).
The screens in this section run on Expo SDK 57 6,418 (React Native 0.86.3) on the Android 16 emulator, and they end with BookNest's reading-notes screen.
