本地静态资源（推荐生产环境离线/内网部署）：

- 当前锁定版本：label-studio-frontend@1.7.1

- 资源来源（示例）：

- https://unpkg.com/label-studio-frontend@1.7.1/dist/lsf/css/main.css

- https://unpkg.com/label-studio-frontend@1.7.1/dist/lsf/js/main.js

- 放置目录：frontend/public/lsf/lsf/
|
|
- TEXT（DataMate 当前默认只用 TEXT）通常只需要：
|
|
- css/main.css
|
|
- js/main.js
|
|
- 如果后续启用音频/更多功能导致按需加载 404，再补齐 dist/lsf 全量目录；常见额外文件：
|
|
- version.json
|
|
- js/478.chunk.js（可选：478.chunk.js.map）
|
|
- js/decode-audio.wasm
