/**
|
||
* AuthStorage 完整实现（基于 unstorage 抽象）
|
||
*
|
||
* SECURITY: 当前与 Dart 端行为一致，refresh_token 以明文存于 localStorage。
|
||
* 后续轮次将升级到 HttpOnly Cookie 方案，参见 `clearAuthData` 处的 TODO 标记。
|
||
*
|
||
* 设计说明：
|
||
* - 内部使用 `SpAsyncUtil` 静态类（@/utils/storage）
|
||
* - 浏览器 → `localStorage` driver；SSR → memory driver（unstorage 自动）
|
||
* - 单例挂在 class 静态字段，规避 HMR 复用污染
|
||
* - `hasXxx` = `token != null && token.length > 0`，对齐 Dart 端 `isNotEmpty` 语义
|
||
* - `clearAuthData` 顺序清理：loginToken → loginProvider → guestToken → refreshToken，任一失败立即返回
