     * Both failures carry 403.
     *
     * wp_send_json_error() defaults to HTTP 200, so a rejected request used to arrive
     * looking exactly like a successful one: jQuery resolved it, the frontend read the
     * error object as data, and an expired nonce was reported to the user as a green
     * success reading "Security check failed". Every other error path in the plugin already
     * carries a status - sendError() defaults to 422 and the exception handler sends
     * 403/422 - and the frontend is written against that, with two dozen handlers
     * reading responseJSON.data.message on failure. These two were the exception.
     *
     * The status is the only thing that changes: wp_send_json_error() builds the same
     * {success: false, data: {...}} body either way, so nothing reading the response
     * has to change with it.
