feat: add Web Vault visibility switch

 - If the site reports a missing `JWT_SECRET`, add it as a **Secret** in Workers settings. In production use a random string of at least 32 characters; do not use temporary or example values.
 
+- To hide the Web Vault, add a text variable named `HIDE_WEB_VAULT` with the value `1` under **Workers settings → Variables and Secrets**. While enabled, server-hosted frontend pages and static assets return `404 Not Found`, while the login, sync, attachment, icon, notification, and other server endpoints used by Bitwarden clients remain available; an already installed or cached PWA can continue using its local frontend. Delete the variable (or change it to anything other than `1`) to restore the server-hosted Web Vault.
+
 - In this flow you hand code to Cloudflare to build and deploy. `wrangler.toml` or `wrangler.kv.toml` in the repo defines binding names; the Worker initializes the D1 schema on first request—no manual SQL upload.

 - 页面提示缺少 `JWT_SECRET` 时，到 Workers 设置里添加 Secret。正式环境至少使用 32 个字符以上的随机字符串，不要使用临时值或示例值。
 
+- 如需隐藏 Web Vault，在 Workers 的“设置 → 变量和机密”中添加文本变量 `HIDE_WEB_VAULT`，值设为 `1`。启用后，服务器上的前端页面和静态资源统一返回 `404 Not Found`，Bitwarden 客户端所需的登录、同步、附件、图标、通知等服务端接口仍可使用；已经安装或缓存的 PWA 可以继续使用本地前端。删除该变量（或将值改为非 `1`）即可恢复服务器上的 Web Vault。
+
 - 这套流程里，用户实际做的是把代码交给 Cloudflare 构建并部署。代码里的 `wrangler.toml` 或 `wrangler.kv.toml` 决定绑定名，Worker 第一次处理请求时会自动初始化 D1 schema，不需要用户上传 SQL。
