[v4] Nextjs CSS minification not working

[welfoz]

Hi everyone!

I want to have minified css to reduce build size and make https://pagespeed.web.dev/ happy.

Tailwind need postcss, so we cannot use the experimental flag "useLightningcss: true"

I tried:

• with or without cssnano
• with or without cssChunking flag
• with or without inlineCss flag
• with "optimize: { minify: false }," for the "@tailwindcss/postcss"

I'm running out of ideas...

Anyone know how to get tailwind css minified with nextjs app router v15?

Thanks a lot in advance!
