histoire is overriding custom font

### Describe the bug

When using `histoire build` we don't see our custom font. It seems to be overwritten by this rule

```
html {
font-size: 1rem;
font-family: 'Noto Sans Display', system-ui, sans-serif;
}
```

This does not happen when we use `histoire dev`.

We are using Vue3, Shadcn, tailwind.

We have tried various approaches to fix it, including importing css from within `histoire.setup.ts`.

Any ideas on how to solve this?

### Reproduction

This only happens using `histoire build` and not `histoire dev`.
Therefore I am not sure how to provide a reproduction.

### System Info

```shell
tailwindcss: ^3.4.3,
histoire: ^0.17.17,
vite: ^5.2.0"
Vue 3
```

### Used Package Manager

npm

Start by reproducing the reported difference between `histoire build` and `histoire dev` with the listed Histoire, Vite, Tailwind CSS, and Vue 3 versions. Inspect the generated build CSS for the `html` font rule; done means the custom font remains effective in the production build without breaking the development behavior.
