    路径前缀是 `/api`。前后端一起发布，不按路径做 API 版本。

    业务 JSON 信封为 `{ code, data, msg, reason }`。`code === 0` 表示成功；失败时 HTTP status 与
    `code` 都表达失败。`code` 默认等于 HTTP 状态；同一状态下的细分原因使用 `status*100+n`
    （例如 40301 配额、42901 限流）。机器判断请用 `reason`，不要解析 `msg`。

    TypeScript 调用面仍是 `web/src/services/api` 的 `http` 模块，不从本规范生成客户端。
