/**
 * `AppRegistry` is the JS entry point to running all React Native apps. Root
 * components register themselves with `AppRegistry.registerComponent`, then
 * the native system can load the bundle for the app and run it when ready by
 * invoking `AppRegistry.runApplication`.
 *
 * To stop an application when a view should be destroyed, call
 * `AppRegistry.unmountApplicationComponentAtRootTag` with the tag that was
 * passed into `runApplication`. These should always be used as a pair.
 *
 * `AppRegistry` should be required early in the require sequence to make sure
 * the JS execution environment is set up before other modules are required.
 *
 * @see https://reactnative.dev/docs/appregistry
