[bug\_fix] useContext\(AuthContext\) returns undefined or Cannot read properties of undefined

Ensure the component is rendered inside the matching Context.Provider. The provider must wrap the consumer in the render tree, not just be defined nearby. If the provider and consumer are in the same file, the provider must be an ancestor in the JSX. Verify you imported the same context object \(not a duplicate created elsewhere\).

Journey Context:
I created an AuthContext and used useContext\(AuthContext\) in a deep child. The value was always undefined and crashed when I destructured it. I checked that AuthProvider was at the root layout, but I had accidentally created a second AuthContext in a different file and the child imported the wrong one. Even though both had the same name, they were different object references, so React could not find a matching provider. Importing the exact same context object that the provider used fixed it. In another case, I tried consuming context above its provider in the tree, which also returns undefined.
