            PrimeVue uses the <i>system</i> as the default <i>darkModeSelector</i> in theme configuration. If you have a dark mode switch in your application, set the <i>darkModeSelector</i> to the selector you utilize such as <i>.my-app-dark</i> so
            that PrimeVue can fit in seamlessly with your light-dark toggle.

        <p>
            An example implementation of a dark mode switch, you may extend it further by involving <i>prefers-color-scheme</i> to keep it from the system initially and <i>localStorage</i> to make it stateful. See this
