To best expose data for rendering in an SFRA-based architecture, especially when dealing with custom attributes such as a special icon for monobrand stores, the recommended approach is to use the module.superModule functionality along with a call method. This approach allows extending the functionality of an existing model without altering the base code directly. By using module.superModule, the developer can add new properties to the Store Model effectively and maintainably, adhering to SFRA's extension and customization best practices.
