Remove Dashicons for Logged-Out Visitors

Stops the Dashicons icon font from loading on the front end for visitors, saving a request. Logged-in users still get it for the admin bar.

Code

add_action( 'wp_enqueue_scripts', function () {
    if ( ! is_user_logged_in() ) {
        wp_dequeue_style( 'dashicons' );
    }
}, 100 );

If your theme uses Dashicons, they are still loaded as a dependency.
