* Yehwang LibreDesk widget 接入脚本（新栈）

|
||
* <script>
|
||
* window.YehwangChatConfig = {
|
||
* baseURL: 'http://localhost:9000',

* inboxID: '10fd5207-d235-4c49-beaa-a65eed0ddd0e',
|
||
* identityURL: 'http://localhost:4100/identity',
|
||
* siteJWT: window.__SITE_JWT__ || null // 站点登录后注入
|
||
* };
|
||
* </script>
|
||
* <script async src="/ai-snippet.js"></script>
|
||
*
|
||
* 有 siteJWT：走 bridge /identity 验签换 LibreDesk widget JWT（生产路径）。
|
||
* 无 siteJWT：匿名访客。
