"""JOOX 歌词（对应 sdk/joox/lyric.ts，上游 joox/lyric.go 移植）。
|
||
|
||
主通道：GET https://api.joox.com/web-fcgi-bin/web_lyric?musicid=<id>&country=sg&lang=zh_cn
|
||
响应形如 ``MusicJsonCallback({"code":0,"lyric":"<base64>"})``，lyric 为 base64 UTF-8 歌词。
|
||
实测（2026-10）：该旧接口仍可用（同域的 web_get_songinfo 已 404，但 web_lyric 未下线）。
|
||
兜底：openjoox2 /track 详情的 ``lrc_content``（同为 base64）。
|
||
解码：base64 → UTF-8 → HTML 实体（& 等）→ ``{ lyric, tlyric: "" }``。
|
||
|
||
QRC（``qrc_content``，XML 格式）上游与 TS 均未解析，此处同样不解析，避免引入未验证逻辑。
