应该都是处理 SVG 时出现的，但是没有定位是哪些 SVG 出了问题，需要再看看。

我确认这个问题可以这样复现

这个分类来看。整体的问题是typst对svg的支持不是特别全

• @font-face：这个的问题是usvg（typst用的svg库）不支持内嵌的字体
• https://developer.mozilla.org/en-US/docs/Web/CSS/letter-spacing：这个好像是svg内嵌text和css的高级特性，应该只在浏览器里面有用
• Selector parsing failed cause invalid ident at 1:27。不知道是啥，可能svg本身是malform的
• Failed to parse font-style value 同上
• Fallback from NewComputerModern10 to Noto Serif CJK JP。字体问题
• Failed to parse clip-path value: 'url("#UNLlygQlUyPx")'. 感觉大概率是svg本身有点毛病
• context-stroke：不知道是什么玩意，网上也搜不到。。

svg是个很复杂的格式。如果svg里面都是矢量的贝塞尔曲线，其实是没什么问题的。但是现在看来我们的svg里面有各种神奇的内嵌字体，css，文字，等等。所以爆了一些warn

context-stroke 可能是这个 https://github.com/OI-wiki/OI-wiki/blob/master/docs/geometry/images/scanning.svg?short_path=8ad9ca2#L9
