🐞[Bug]: Author list formatting uses line break and '&' instead of comma, causing visual inconsistency in article cards

• I have searched the existing issues

Describe the bug

The author list below article titles is currently displayed with a line break and an '&' before the second author's name (e.g.,
Sowmiya Venkatesan
& Sanjay Viswanthan). This is visually inconsistent and breaks the layout continuity between cards. See screenshot for reference.

This affects readability and can be improved for a cleaner look.

Expected behavior

All author names should appear on a single line with a comma (,) rather than an ampersand (&) or line break (e.g., Sowmiya Venkatesan, Sanjay Viswanthan).

The format should be visually clean and consistent across all article cards. Please choose the most aesthetically pleasing approach (likely, all names in one line separated by commas).
