Build me a simple web app for a university certificate system where an admin can log in, bind a crypto wallet, and issue student certificates that get minted as NFTs on Aptos devnet.

I want a landing page with separate portals for admin, student, and employer. The admin should be able to enter student details, mint the certificate, generate a nice PDF certificate from a template, email it to the student, and save the record so it can be viewed later in a dashboard. Students should be able to look up their certificates by email and see what was issued to them. Employers should be able to verify a certificate using the student email and transaction hash, then get a clear result with the certificate details and a link to the Aptos transaction.

Use a clean modern UI with a dark and light theme toggle, and make the certificate design look polished. If anything needs current library or API details, look them up online and use the latest docs.
