// 喜马拉雅曲目信息（PC 桌面端 baseInfo 通道）

// 接口: https://www.ximalaya.com/mobile-playpage/track/v3/baseInfo/{ms_ts}?device=win&trackId=&trackQualityLevel=1
|
||
// 实测（2026-10-02）匿名免费曲目可用，但必须同时满足：
|
||
// 1) 携带 PC 设备 Cookie（install_id 与 1&_device 同一 uuid，channel=99&100001，客户端 4.0.14 抓包格式）
|
||
// 2) 携带 du_web_sdk 真实 xm-sign（hdaa 上报取 cadd/sid）
|
||
// 缺 Cookie 或换 device=www2 均返回 ret=1001 系统繁忙。
|
||
// 响应 trackInfo 顶层挂载（playUrlList/title/cover*/duration/isPaid/isAuthorized/isXimiUhqTrack），
|
||
// playUrlList[].url 为 AES-ECB 加密地址（key 取自官方客户端 4.0.14 asar），见 decoder.ts
