v4: Automatic content detection in turbo.build sveltekit monorepo - works in dev, but not build/preview

[mafifi]

Hi,

I followed the advice outlined in, issue 13136, and the docs, for my monorepo.

The structure is as follows,

apps
-laifu-nini
--src
---app.css
packages
-ui
--tailwind.css
--components
---{a load of sub-directories of svelte files}

To remove the complexity of turbo, I'm showcasing with npm in the app directory.

In dev, this works perfectly

cd apps/laifu-nini
npm run dev

In preview, this doesn't see the classes in my components and shakes them out...

cd apps/laifu-nini
npm run build
npm run preview

apps/laifu-nini/src/app.css

@import '@repo/ui/tailwind.css';

packages/ui/tailwind.css

@import 'tailwindcss' source('../../');
@import './css/fonts.css';
@plugin 'tailwindcss-animate';

@theme {
...
}

I am confident it's not a bug, but something I am doing. Any ideas would be much appreciated!
