WHY YOU NEED A CUSTOM CONTEXT PROVIDER

"Naked" React Context providers can be bad for performance due to unnecessary re-renders. Using custom context providers, which hold state management logic within a dedicated component, improves separation of concerns and prevents unrelated components from re-rendering. This approach uses component composition to make sure only context consumers update when the context value changes.
