         * SMTP 主机/账号/密码，但新值还没写进库（register_setting 的
         * sanitize 回调返回值之后才落库）。直接读库会拿到上一次的配置，
         * 于是"明明填对了却发不出去"。
         *
         * 为什么不用 update_option() 把新值先写进去：那个函数会再触发
         * 一次 sanitize_option_kratos 过滤器，而写入逻辑本身就在那个
         * 回调里 ⇒ 无限递归吃爆内存（3.2.11 的事故）。
         *
         * 覆盖层只在本请求内有效、不落库、不触发任何过滤器，
         * 所以安全。其它场景这个全局变量根本不存在，行为与原来一致。
