• Added a search bar to filter contributors by name.
• Updated JS to handle dynamic rendering of cards based on search and page selection.
• Minor CSS adjustments for better responsiveness and card display.

Benefits

• Makes it easier to find a specific contributor.
• Enhances mobile and desktop usability.

Testing

• Verified that pagination updates correctly when filtering via search.
• Confirmed responsive card layout on different screen sizes.
