/**
|
|||
|
|
* `web/i18n.js` 的品牌文案渲染回归（2026-09-19，档案 134 配套）。
|
|||
|
|
*
|
|||
|
|
* 为什么单独钉这一条：品牌标识从 DeepSeek 图形换成了**文字**（中文「能力枢纽」／
|
|||
|
|
* 英文及其他语言 `CapabilityNet`）。词条漏配或 key 写错时，i18n 会**静默回退英文**
|
|||
|
|
* —— 页面上看不出报错，只有中文用户看到英文名。这类"静默失败"必须靠测试钉住。
|
|||
|
|
*
|
|||
|
|
* 做法：用 `node:vm` 跑**仓库里那份真实的 `web/i18n.js`**（不是复制一遍逻辑），
|
|||
|
|
* 配一个够用的最小 DOM 桩，断言六种语言解析路径下的**实际渲染结果**。
|
|||
|
|
*
|
|||
|
|
* ⚠️ 桩里必须注入 `URLSearchParams` / `URL`：`vm` 上下文只含 ECMAScript 内置、
|
|||
|
|
* 不含 Web API；少了它们 `new URLSearchParams(location.search)` 会抛 ReferenceError，
|
|||
|
|
* 被 i18n.js 的 try/catch 吞掉 ⇒ 表现为"`?lang=` 不生效"的**假失败**（第一版踩过）。
