+/* ===================== 鉴权接口（真实后端 · 不走 mock） =====================
  * 落实规范第 4、5、6 节。全部走 http 层；匿名接口显式 auth:false。
  * 客户端不提交 role / userId / verified / passwordHash（后端生成）。
+ *
+ * 鉴权域已整体切真实后端（2026-09-30）：短信网关、/auth/login、/auth/me、
+ * /auth/refresh、/auth/logout、/auth/identity/select、/auth/company/register
+ * 均已接通。本文件函数不再受全局 isMockMode() 控制，永远走真实接口；
+ * 业务域（api.ts 内未接通的接口）仍按 isMockMode 兜底 mock。
+ * 故 mockAuthTokens 辅助函数已删除——鉴权域不再有 mock 形态。
