/**
|

* 视频通话美颜设置
|
||||
*
|
||||
* 全部效果（磨皮/美白/红润/瘦脸/口红/腮红）默认由本地管线处理：
|
||||
* MediaPipe Face Landmarker（开源免费）识别人脸关键点 + WebGL/Canvas 逐帧渲染，
|
||||
* 经 getUserMedia 拦截注入通话视频流（见 utils/beauty/ 目录），预览所见即所得。
|
||||
*
|
||||
* 仅当浏览器不支持 WebGL 时，磨皮/美白/红润回退到腾讯云 TRTC 免费 BasicBeauty
|
||||
* 插件（TUICallEngine.setBeautyLevel）。不依赖付费的腾讯特效 SDK。
