In what area is the section rule for a dashboard widget stored?

The section rule for a dashboard widget is stored in the same class as the harness of the portal because the dashboard functionality is closely tied to the specific context of the portal's user interface. Each portal harness serves as the primary container that organizes and displays various UI elements, including dashboards, which are made up of sections that define the layout and content. By storing the section rule within the same class as the portal harness, it ensures that the dashboard widget can effectively reference and integrate with the overall design and behavior of the portal.

This design choice allows for greater reusability and maintains a coherent structure within the application, as it aligns the dashboard components with the intended user experience defined by the harness classes.
