Huddle — front-end licenses / 前端许可说明
==========================================

The Huddle web front-end (everything served under /static/: HTML, CSS, JavaScript,
and the bundled processors.js built from web/vendor-src/) is licensed under the
GNU General Public License, version 3 (see LICENSE-GPL-3.0.txt), because it uses
Robust Video Matting (GPL-3.0) for the "Quality" virtual-background mode.
The server-side code is not distributed to users and is not covered by this notice.

Huddle 网页前端（/static/ 下的全部 HTML、CSS、JavaScript，以及由 web/vendor-src/ 打包的
processors.js）按 GNU 通用公共许可证第 3 版（GPL-3.0，见 LICENSE-GPL-3.0.txt）授权，
原因是“质量优先”虚拟背景使用了 GPL-3.0 的 Robust Video Matting。服务器端代码不分发给用户，不在此列。
