    iOS 客户端实际调用的远程接口契约。

    维护规则：
    1. backend 路由、请求字段或响应字段变化时，先更新本文件，再更新 Swift 模型。
    2. 所有 JSON 接口使用统一响应 `{code, message, data}`。
    3. 除登录、注册和刷新令牌外，接口均使用 Bearer access token。
    4. 公网网关保留 `/celestia-trace/v1`；后端 Gin 路由本身使用 `/v1`。
    5. 服务端时间使用 RFC 3339 / ISO 8601，客户端同时兼容带或不带小数秒。

        return the asset directly; the iOS decoder intentionally accepts both.
