+/**
+ * next-intl 请求配置（App Router 无 i18n 路由模式）
+ *
+ * ARCHITECTURE.md §3.4 V3-A6：next-intl 正式接入
+ *
+ * 采用"无 i18n 路由"策略（locale 不出现在 URL 中）：
+ * - locale 由 NEXT_LOCALE cookie 决定（locale-switcher 写入）
+ * - 缺省 locale = zh-CN
+ * - 切换 locale 时设置 cookie + router.refresh() 触发 RSC 重新渲染
+ *
+ * 关联：portal-shell ARCHITECTURE.md §3.4 V3-A6、§8.7、§11.2
