XLBoosterPro/Certificate ? reverse-engineered prompt

Build me a simple certificate page or small site for managing and showing certificates.

I want it to feel clean and professional, like something that could be used to view or print a certificate for a person. The main thing should be a polished certificate layout with space for a name, title, date, and any other details that make it look official. If it helps, make it easy to update the text so I can reuse it for different certificates later.

Please keep it simple and tidy, with a nice presentation that works well in a browser and looks good when printed. If there’s anything unclear, use sensible defaults and look up current docs online if you need to.
