          Render pages with mock data. This makes it easy to build and review
          page states without needing to navigate to them in your app. Here are
          some handy patterns for managing page data in Storybook:
        </p>
        <ul>
          <li>
            Use a higher-level connected component. Storybook helps you compose
            such data from the "args" of child component stories
          </li>
          <li>
            Assemble data in the page component from your services. You can mock
            these services out using Storybook.
          </li>
        </ul>
