Adds a predictable body class when visitors are logged in so themes can target member-only UI states without template edits.

add_filter( 'body_class', 'wpfolks_add_logged_in_body_class' );

function wpfolks_add_logged_in_body_class( $classes ) {
    if ( is_user_logged_in() ) {
        $classes[] = 'is-logged-in-user';
    }

    return $classes;
}
