Issue using lightningcss with Storybook

[smarlhens]

Hey there 👋🏻

Thanks for your amazing job on this library.

I am trying to use the new lightningcss: true option in config but I am facing an issue: it seems that with my current configuration I'm not getting any style in my storybook story: stackblitz repro repo.
Using postcss as mentioned in the documentation https://panda-css.com/docs/installation/storybook it is working well.
Do I need to change something else to make it work ?

As the lightningcss seems to be experimental (not enabled by default) I have decided not to open an issue but a discussion.

Thanks in advance for your help 🙏🏻

Wish you a great day ☀️ ☮️

the only thing needed to use lightningcss is to set lightningcss: true in your config, you don't have to update anything else

postcss is used in 2 different ways with Panda:

1. internally for some CSS transformations using AST, this is the part that changes by using lightningcss: true
2. externally as a distribution mechanism (@pandacss/postcss or its alias @pandacss/dev/postcss), as an alternative to the CLI, you can still use lightningcss: truewith the@pandacss/dev/postcss` plugin

Thanks, so I still need to use PostCSS as a distribution mechanism then. I had deleted the postcss.config.cjs in my repro repo… I will revert this change.
Thanks for your answer, wish you a great day 👍🏻
