Dolldats/JCS-Certificate-System ? reverse-engineered prompt

Build me a certificate management system for Jama’at events and auxiliaries.

I want a web app where people can sign in, sign up, and then use a dashboard to manage events, participants, certificate templates, issued certificates, administrator access, and audit history. It should let admins create and edit events, import and verify participants, design certificate layouts, generate certificates in bulk, preview and print them, verify or revoke them, and manage who has admin access. I also want a simple member portal so regular members can see their event participation and certificate status, and download or print their own certificates when allowed.

Please make it feel polished, responsive, and easy to use, with a light and dark theme. If you need current docs for anything, look them up online. Use the existing backend structure for the API side and make the frontend talk to it cleanly, with sensible fallback behavior if some data is missing.
