/**
 * `react-native-live-activity-kit` — public client API.
 *
 * A thin, fully-typed wrapper over the single Nitro HybridObject. It normalizes
 * friendly options into the flat native config, ref-counts event subscribers
 * behind a single native callback per event, and converts native optionals into
 * the `null`-shaped public types. Live Activities are iOS-only; every method is
 * a safe no-op (or a typed rejection) on Android and web.
 *
 * The matching server sender lives at `react-native-live-activity-kit/server`.
