+/*
+ * When we request push notification permissions with
+ * `provideAppNotificationSettings: true`, iOS adds an in-app notification
+ * settings button to the system Settings screen for Bluesky (and may surface
+ * it elsewhere, e.g. from a delivered notification). Tapping it launches the
+ * app and calls `userNotificationCenter(_:openSettingsFor:)`.
+ *
+ * expo-notifications owns the `UNUserNotificationCenter` delegate via its
+ * `NotificationCenterManager`, which fans that callback out to any registered
+ * `NotificationDelegate` through `openSettings(_:)`. We register here and turn
+ * the callback into a `bluesky://settings/notifications` deep link so the app's
+ * existing linking config routes the user to the notification settings screen.
