Response subset a guarded fetch resolves to — members every fetch implementation provides. The guard returns the base fetch's response OBJECT untouched (it only reads status + the location header off intermediate 3xx hops), so a connector needing more (streaming body, clone) can safely cast back to its own runtime's Response type — the underlying value IS that Response, nothing is wrapped or consumed.
