Контракт

• createRoot is exported from react-dom/client and is absent from the react-dom root entrypoint
• flushSync around root.render commits the root DOM before flushSync returns
• createPortal places its child in a separate target while preserving context from its React ancestors
• a click from a portal child bubbles to its React ancestor despite separate DOM ancestry
• root.unmount synchronously removes both root and portal DOM
• root.render after root.unmount throws Cannot update an unmounted root
