Why is the code in the article not highlighted?

First of all, thank you for this open source project that provided me with the inspiration to build my own blog!!

I noticed that the code in your online deployed blog post was not highlighted. What's going on?

And I also use nuxt-content as my CMS, and use @tailwindcss/typography as the .md style renderer. It can be highlighted normally in the dev environment, but once deployed to vercel, I will find that it cannot be highlighted.

you can see that there is no shiki classes.

this is the normal condition in dev env.

I don't know whether you've encountered the same problem as I have? but I don't know how to solve it (T o T)

I found that when I build it and preview at localhost:3000 it works... I think it might be a Vercel deployment issue??????
