 * Uninstall — runs only when the plugin is deleted from the WordPress admin.

 * The plugin stores no settings. The only data it leaves behind is the
 * short-lived, per-user result notice, so that is all this removes.
 *
 * The network itself (wp-config.php constants, .htaccess rules and network
 * tables) is deliberately left alone: it is the site's configuration now, not
 * plugin data, and removing it would break every site on the network.
