Hi Dan Burzo!
I've encountered strange issue when using latest culori with Next.js in production build only. I've created minimal reproduction of the issue (see the repo below).
How to reproduce
Dev
If you run the app with npm run dev command it works as expected, the converter converts the color with no problem in both the culori and culori/require usage.
Prod
However if you run the production build npm run build && npm run start the culori ESM version throws an error but the culori/require version still works as expected.

I'm not sure if this is an issue with Culori or Next.js, but I've figured I'll ask you first.
Thanks for creating this great package!
