 * Uninstall — runs only when the plugin is deleted from the WordPress admin.
 *
 * Unlike most plugins, deleting this one must NOT drop its tables by default.
 * The archive tables hold the merchant's real order data; dropping them on an
 * accidental delete would be catastrophic and unrecoverable. So the archive
 * survives uninstall unless the merchant explicitly opted in beforehand.
 *
 * The archive browser offers "Restore all" as the safe exit route, and the
 * settings screen only offers the opt-in once the archive is empty.
