The failing CI checks appear to be unrelated to this frontend fix.

The errors are caused by missing backend modules:

• backend.models.vendor_profile
• routes

My changes only modify blog.js and do not affect the backend Python code.

The blog page has been tested locally:
✅ Blog posts display correctly
✅ Dark mode works
✅ Load More button works
✅ Category filters work
