Automated E-commerce Analytics Event Tracking with Zustand Middleware

Act as a Marketing Data Engineer. Architect a bespoke, highly transparent Zustand middleware wrapper that autonomously intercepts state mutations and triggers real-time [ANALYTICS_SDK] (e.g., Google Analytics 4, Segment, Mixpanel) tracking calls. The middleware must execute a switch statement filtering explicitly for high-value actions defined in the [TRACKED_ACTIONS_LIST] (like 'ADD_TO_CART' or 'INITIATE_CHECKOUT'). Map the raw Zustand state variables via a precise [PAYLOAD_MAPPING] function into the exact JSON schema demanded by the analytics provider's API. This tracking architecture must be completely decoupled and invisible to the React UI developers, handled entirely at the state mutation layer to ensure 100% analytics coverage without littering the component tree with tracking code.
