Summary
react/react-dompeerDependencieswith^19.0.0(keeping 16/17/18).RefObject<T>→RefObject<T | null>) in public and internal types so consumers on@types/react@19get clean type-checking —useRef<T>(null)returnsRefObject<T | null>in v19. Backward-compatible with@types/react@18(covariant assignment).JSX.ElementwithReact.ReactElementinNotificationspublic types —@types/react@19removed the globalJSXnamespace.<button ref>and TokenizedInput Wrapper's native<div ref>) needed for@types/react@18LegacyRef<T>variance — commented inline.devDependenciesare intentionally not bumped —react/react-dom/@types/react/@types/react-domstay on^18, matching the approach used in@gravity-ui/uikit. The library is verified against React 19 ad-hoc (see test plan); the dev stack continues to develop and test against React 18.
