"""界面回归检查（开发/验收用）：布局几何 + 像素颜色区域校验 + 截图。
|
||||
|
||||
AI 无法直接查看截图，所以这里用两种可判定的方式验证界面确实渲染正确：
|
||||
|
||||
1. 遍历控件树，检查是否有零尺寸 / 越界 / 被横向裁掉的控件，
|
||||
并用字体度量核对关键文本（大号计时器、状态栏）不会被截断；
|
||||
2. 读取渲染结果的像素，按区域统计颜色，确认电平条、录音按钮、
|
||||
示波器、整段总览等自绘控件确实画出了预期颜色。
|
||||
|
||||
还会真实录音 2.6 秒，验证「开始录音 → 界面刷新 → 停止 → 仪表冻结」链路。
|
||||
|
||||
用法::
|
||||
|
||||
python dev/gui_check.py # 离屏运行，不需要显示器
|
||||
python dev/gui_check.py --shots # 额外把截图存到 dev/shots/
