// @name         DDDD OCR WEB - 验证码自动识别
// @namespace    https://github.com/MakotoArai-CN/ddddocr-webjs
// @version      1.0.2-beta-build1764699797247
// @author       MakotoArai-CN
// @description  自动检测并识别页面验证码，自动填充到输入框。首次使用需设置白名单，会自动下载约50MB模型文件以及20MB左右的ONNX推理运行时文件，但是不推荐自动下载，可能很慢，建议手动下载并上传（详见项目文档）。如果弹出窗口提示授权请授权给脚本。
