感谢各位的报告！我们已经找到了问题所在，并且正在修复中：

> <https://github.com/discourse/discourse/pull/34438>
>
> We were already polyfilling \`light-dark\` for older browsers. However, that polyf…ill makes use of native CSS nesting, which is also unsupported by older browsers. This commit adds the \`postcssNesting\` transform to turn that nesting back into flat CSS.
> 
> This became a noticable problem since light-dark was added to a critical core stylesheet in 1ec69c3f2f32c48b68596d639e1e495dc031f4ed, which then caused the whole file to be a syntax error under Safari 16.

此修复也将向最近发布的稳定版本回溯移植。
