- queueForOffline now saves url, method, headers, body (replay-safe for localStorage); legacy items with options only still replayed via fallback - processOfflineQueue builds fetch options from stored method/body so replayed requests send the same payload when back online - Make queueForOffline async and await it in handleFetchResponse/handleFetchException - Add tests asserting queue stores method/body and replay uses them
