                // Unified API exploration
                const hub = openSpecHub({
                  specs: [
                    'openapi.yaml',
                    'asyncapi.yaml',
                    'events.yaml'
                  ]
                });
                
                // See all operations
                hub.getAllOperations();
                // → 9 operations unified
