One is a React framework for web, iOS, and Android apps.

import type { HybridObject } from 'react-native-nitro-modules'
import type { HingeState, SizeClass } from '../adaptive/types'

// window size class and hinge state behind useSizeClass/useHinge.
// getInitial* are synchronous seed reads, evaluated once at JS import so the
// first render already measures real (mirrors safe-area initialWindowMetrics).
// a one-shot read plus change listeners: the first listener starts the
// platform monitor and the last removal stops it, so the first event can
// never race the subscription. add*Listener returns its remover.
// hinge is undefined when the device has no hinge.
