expo-app-design: CSS/Tailwind contradiction + missing stability warnings

[nqh-packages]

Hey! Found some confusing bits in the expo-app-design plugin while going through the skills.

The main thing

building-ui/SKILL.md says:

CSS and Tailwind are not supported - use inline styles

But then there's a whole tailwind-setup skill showing how to set up Tailwind CSS v4 + NativeWind v5. So... which is it?

I get that native className isn't supported out of the box, but the current wording makes it sound like Tailwind is impossible when it's not.

The other thing

The tailwind-setup skill recommends these packages without any heads up about stability:

nativewind@5.0.0-preview.2
react-native-css@0.0.0-nightly.5ce6396

That's a preview and a nightly. Probably worth a warning that this isn't production-ready yet, and that you need RN 0.81+, Reanimated v4+, and New Architecture.

Small thing

The gradients reference requires New Architecture but the building-ui skill doesn't mention that when listing the references. Easy to miss.

Happy to PR these fixes if you point me to which approach you'd prefer.

I too have the same issue, I would be very happy about a fix :)
Alternatively, I think temporarily removing the tailwind-setup skill would prevent other people from having those same bugs.
