F fqh feat: Star Music PC v1.3.0 首次提交（Wails v2 桌面端） 2 天前
1/**
* uni.* 兼容层（PC 版）
*
* 目标：让从 uni-app 移动端移植过来的 common/* 业务代码「零改动」运行在 Wails(WebView2) 里。
* 提供的能力与移动端语义保持一致：
*   - 存储：内存表 + 防抖落盘到 localStorage（同步 API，语义与 uni 一致）
*   - 音频：HTMLAudioElement 适配成 InnerAudioContext
*   - 网络：优先走 Go 侧原生 HTTP（绕开 CORS），不可用时回退 fetch
*   - 交互：toast / loading / modal 交给 Vue 层渲染（见 uni/ui-state.js）
*   - 原生：文件对话框、下载到磁盘、剪贴板、窗口控制（见 uni/native.js）
*
* 必须在任何 common/* 模块之前被 import（main.js 的第一行）。
*/
