• Types: @types/react is an optional peer dependency - the type declarations import from react, and with pnpm's global virtual store (virtualStoreType: global) TypeScript resolved that to the untyped react/index.js, so the React types in them became any. Under the default pnpm layout it only worked through pnpm's hidden hoisting. The range is *, so projects without TypeScript install nothing extra and an older @types/react does not make npm fail. The same fix as react-i18next 18.0.1 (react-i18next#1948)
• Tested with i18next 27.0.1 and react-i18next 18.0.1 - the dev dependencies and all examples use them. The peer ranges are unchanged.
