What is Context and when would you use it?
Model answer
Context lets a parent share a value with all components below it without passing props at every level. You create it with createContext, provide a value with a Provider, and read it with useContext.
Good uses: theme, current user, language. It is not a complete state manager, and every consumer re-renders when the value changes.
