const { withAndroidManifest, AndroidConfig } = require('expo/config-plugins')

// Why: Expo's top-level `orientation` only emits portrait/landscape/unspecified.
// "unspecified" still auto-rotates on many Android devices even when the system
// rotation lock is on. "fullUser" honors the user's auto-rotate setting (no
// rotation when locked) while still allowing every orientation when unlocked —
// matching the iOS UISupportedInterfaceOrientations behavior. iOS is untouched.
const ANDROID_SCREEN_ORIENTATION = 'fullUser'
