 - **物理验证**：模拟操作前必须确保窗口已通过 `activate()` 置于前台。
 - **偏移量**：所有的相对偏移像素值（如“向右移动 10 像素”）同样需要除以 `dpi_scale`。
 - **坐标对齐**: 物理坐标 = 截图坐标；ljqCtrl 自动处理 DPI 换算，禁止手动重复计算。
+- **⚠️ 窗口坐标转换陷阱**：使用 `win32gui.GetWindowRect(hwnd)` 获取的矩形包含标题栏和边框，而截图内容是客户区。点击截图内元素时，必须用 `win32gui.ClientToScreen(hwnd, (0, 0))` 获取客户区原点的屏幕坐标，再加上截图内坐标。禁止直接用 GetWindowRect 左上角 + 截图坐标。
