[Bersaelor]

When checking out your project I first tried yarn:

❯ yarn
yarn install v1.22.19

[vite:css] Failed to load PostCSS config (searchPath: ../chromeextension): [Error] Loading PostCSS Plugin failed: Cannot find module 'tailwindcss'
Require stack:

(@/...chromeextension/postcss.config.cjs)
Error: Loading PostCSS Plugin failed: Cannot find module 'tailwindcss'
Require stack:

and it didn't work.
With npm it seemed to work fine. I use nvm, so it correctly detected the projects .nvmrc to use v16.16.0
