-`CROSSDESK_UI_CAPTURE_DEMO_ASSETS` 必须指向包含上述图片的目录。缺失图片会让捕获命令失败，避免再次导出空白缩略图；不设置该变量时，仍保留原有测试状态。
+`CROSSDESK_UI_CAPTURE_DEMO_ASSETS` 必须指向包含上述图片的目录。缺失图片会让捕获命令失败，避免再次导出空白缩略图；不设置该变量时，仍保留原有测试状态。捕获工具会先运行窗口事件循环，等待尺寸与缩放初始化；直接在 `show()` 后截图可能得到 1× 图片。
 
 捕获模式兼容 `/tmp/crossdesk-ui-capture-page` 和 `/tmp/crossdesk-ui-capture-language` 两个旧覆盖文件；如存在，它们会优先于环境变量，运行前请检查。更新后逐张检查文字、布局、敏感信息和文档引用，并同步修改本页日期与源码版本。
