 * Client-side i18next provider for App Router.

 * i18next-locize-backend, or i18next-chained-backend to load translations
 * from external sources.
 *
 * @example
 * ```tsx
 * // In app/[lng]/layout.tsx (Server Component)
 * import { I18nProvider } from 'next-i18next/client'
 * import { getT, getResources } from 'next-i18next/server'
