🐛 bug report

I am trying to use https://unocss.dev/ with it's postcss plugin. Currently parcel can't resolve node:fs/promises which is used by unocss postcss plugin.

🎛 Configuration (.babelrc, package.json, cli command)

{
  "name": "exampleproj",
  "private": true,
  "version": "0.0.0",
  "scripts": {
    "start": "parcel index.html",
    "build": "parcel build index.html --no-source-maps --detailed-report",
    "serve": "parcel serve index.html"
  },
  "devDependencies": {
    "@parcel/optimizer-data-url": "2.0.0-nightly.1290+94b3ac40a",

Bumping this because I too would like to use Parcel and UnoCSS. Not sure what a good workaround would be, but I'll take any suggestions!
