sam-1510-hash/Orphan-Helper ? reverse-engineered prompt

Build me a community platform for orphanages where supporters can log in, browse real needs from different orphanages, and help fulfill them in real time. I want secure sign up and login, with different roles for regular supporters and orphanage staff or admins, so each person only sees what they should. The app should let orphanages post and update children’s needs, let donors send donations online, and show a clear history of what has been given and what impact it made. It should also support child sponsorship, send automatic email updates when something changes, and generate a PDF receipt after a donation. Make it look clean and responsive on phones and desktops. Use the existing MERN stack setup in the repo, and if you need to check current best practices for any library or integration, look them up online first.
