nginx 侧全自动（snippet 剥离/内部 vhost 补回/admin 局部/失败回
滚/源站终验），ESA 三动作打印手动步骤；dry-run 先行+确认门。

验证: bash -n 语法过；dry-run 输出与 Phase 5f T1 操作单变更计划一致

Spec: none (用户操作单自动化，Phase 5f T1 收尾件)

+==== ⑥ 剩余手动步骤：ESA 控制台（无法脚本化）====
+  1. 全站 purge：wait4x.online（不做的话 noindex 头在边缘再活 30 天）
+  2. HTML 边缘缓存 TTL 调 ≤1 小时（当前 30 天）
+  3. 加规则：/artalk/api/* 路径绕过缓存（pv 数字不再冻结）
+  4. 顺带查 git.wait4x.online 为何 522（源站健康/回源配置）
+
+完成后告诉 research：将跑生产 Lighthouse 入档（预期 SEO 60→95+）。
