CSS not loading properly on Hashnode headless CMS setup (Enterprise Theme + Vercel)

Hi,
I’m using Hashnode for my blog and configured it as a headless CMS (after dozens of configuration attempts — finally got it working).

My website is: https://psikologduyguaksoy.com/blog
I’m using the Enterprise theme, and hosting the site on Vercel.

However, the CSS is not loading properly, and I couldn’t find any solution :(

Configuration

Here’s how I configured it on Vercel:
`NEXT_PUBLIC_HASHNODE_GQL_ENDPOINT=https://gql.hashnode.com
NEXT_PUBLIC_HASHNODE_PUBLICATION_HOST=blog-duygu-aksoy.hashnode.dev
NEXT_PUBLIC_BASE_URL=/blog
NEXT_PUBLIC_MODE=development`

Thank you
