What functionality does the framework provide for managing UI patterns?

The framework provides pre-defined widgets for standard patterns, making it easier for developers to implement consistent and common design elements across their applications. These widgets are tailored to follow best practices in user interface design, allowing for quicker development and a more unified look and feel throughout the application. This not only enhances user experience but also saves time, as developers can leverage these ready-to-use components rather than creating them from scratch.

In contrast, unlimited customization options for individual components is not a primary feature, as the framework focuses on efficiency and consistency through standardized widgets. Mandatory data integration requirements for all apps is not relevant to UI pattern management, as it pertains to back-end data handling rather than front-end design patterns. Lastly, supporting only one type of device does not align with modern development practices; the framework is designed to facilitate responsive design, accommodating various devices and screen sizes.
