I would like to propose adding an optional metadata badge displaying the contributor’s first contribution date to the contributor card (e.g., Est. 2024).

Proposed Changes:

• Add a small badge to the top-right section of the card.
• Render it conditionally — only when the corresponding data is available.
• Reuse the existing badge styling for visual consistency.

Visual Changes:

I’m happy to implement this if it aligns with the project’s design direction. I would appreciate feedback before proceeding with a PR.
