//! 「**模型这一层会给出什么**」的取样器：视图模型字段 + **按码做的 i18n 查表**，拼成一串。
//!
//! ## 边界（复审 r2 P2-2 订正，别把这条读成「视图覆盖」）
//!
//! 这是**平行实现**：它自己调 `catalog` 查表，**不调用** `login::panel` / `forms::status_line`，
//! 也不遍历 iced 的元素树。所以它证明的是「模型 + i18n 表里没有中文」，**不证明**「视图真的照它画」。
//!
//! 视图层靠两道别的闸：
//! 1. **类型**：`DevicePanel` / `AuthlibPanel` 里**没有** `message`/`detail` 字段（r3 删掉了），
//!    想画后端原文是编译错误，不是测试问题；
//! 2. **出图**：`DevDocs/artifacts/m114/after/*` 由人（tower/复审）逐张看。
//!
//! 为什么单独一个文件：`pages/account/tests.rs` 贴着 400 行硬线，而这段是**纯取样**
//! （不给任何断言）——断言都在 `tests.rs` 里。
