@amanmahajan7 rolldown seems to work great now!
I'll open a few issues upstream first.

[amanmahajan7]

Is the bundle same as before?

[amanmahajan7]

nice!

[nstepien]

Is the bundle same as before?

I've compared the bundle output after running prettier on the output files:

• no changes in CSS output
• we lost PURE annotations ([Feature Request]: pure annotations rolldown/rolldown#3201) in js files
• we lost babel-plugin-optimize-clsx
• otherwise I couldn't find any really meaningful differences, just some braces or formatting changes and other smaller stuff.

[amanmahajan7]

Maybe we can manually optimize clsx calls. Not sure how much difference it makes in performance though

[nstepien]

Probably not worth the effort.
