- console/wrangler.jsonc 填入真实 D1 id + 自定义域名 routes.custom_domain + PUBLIC_BASE_URL
- README 生产部署章节补线上实例与自检命令(含 database_id 占位会导致 Invalid uuid 的坑)
- 版本号 2.1.1 -> 2.1.2

 // WmailHub Console —— Cloudflare Workers 部署配置(生产)
 // 本地开发不需要 wrangler:直接 `bun run dev`。首次部署前:
-//   1. `bunx wrangler d1 create wmailhub`            -> 填 database_id
-//   2. `bunx wrangler r2 bucket create wmailhub`
-//   3. `bunx wrangler d1 execute wmailhub --remote --file=./migrations/0001_init.sql`

 //   4. `bunx wrangler secret put SESSION_SECRET`      (>=32 位随机串)
 //   5. 配置 CF_OAUTH_CLIENT_ID/SECRET/REDIRECT_URI vars(真实 OAuth;缺省走 sim)
