Describe your issue
A few months ago this issue was fixed that allowed to use Tailwind v4 in Stackblitz: windlabs/tailwindcss/issues/13133
Unfortunately, it only works for a basic/default tailwind config and comes with a limitation: I cannot parse my design system library (a dependency) using @source (@source './node_modules/@spark-ui';).
The styles are not there for some reason. It has been a pain point for us this whole year because we were using Stackblitz as a bug reproduction environment for our users, and now we simply have no mean to do so (We had no issue with v3).
