Describe the Bug

Hi! I made a fresh 1-click deploy of the new cloudflare template and it seems like the styles from the frontend folder are being loaded in the admin panel. I've made a fresh clone of the blank template and this problem does not happen.

• The Login page has a black background with black text in light mode
• Font base size is set to 18px rather than the default 13px
• Removing the styles.css file from src/app/(frontend) fixes the problem, removing the import in both src/app/(frontend)/layout.tsx and src/app/(frontend)/page.tsx does not fix the problem.
• Thought it might have to do with cssChunking in Next, but tried setting it to both false and 'strict' and neither made any change.
