Describe the bug

Stylesheets are not included on the backend during production builds if the project uses layouts. If the contents of layouts are transferred to app.vue everything works as expected. The problem appeared since version 3.10

Would you be able to provide a reproduction? 🙏

More info

Why do I need to provide a reproduction?

Reproductions make it possible for us to triage and fix issues quickly with a relatively small team. It helps us discover the source of the problem, and also can reveal assumptions you or we might be making.

What will happen?

If you've provided a reproduction, we'll remove the label and try to reproduce the issue. If we can, we'll mark it as a bug and prioritize it based on its severity and how many people we think it might affect.

If needs reproduction labeled issues don't receive any substantial activity (e.g., new comments featuring a reproduction link), we'll close them. That's not because we don't care! At any point, feel free to comment with a reproduction and we'll reopen it.

How can I create a reproduction?

We have a couple of templates for starting with a minimal reproduction:

👉 https://stackblitz.com/github/nuxt/starter/tree/v3-stackblitz
👉 https://codesandbox.io/s/github/nuxt/starter/v3-codesandbox

A public GitHub repository is also perfect. 👌

Please ensure that the reproduction is as minimal as possible. See more details in our guide.

Unfortunately, I can’t reproduce this error on a new project, but I noticed this oddity. If I remove all the scss code from the style tag in layout, then everything starts working correctly, but if I add at least one class there, then default.css stops being generated in the production build.
it's with scss in layout


it's without scss

Possibly because of this: #25724

Can you check if after build the folder .nuxt/dist/server/_nuxt contains a .vue file that should be a js file with a stylesheet import in it?
