yassyasar10-lang/project ? reverse-engineered prompt

Build me a full stack lost and found web app where people can report items they lost, post items they found, and search for possible matches. I want a clean dashboard for regular users and an admin view for moderating reports and claims. The app should let users create, edit, and track reports, get live updates when new items are posted, and see matching suggestions between lost and found entries.

Please make the frontend feel polished and modern, with smooth animations, a map view for item locations, and a few simple charts or stats for activity. On the backend, set up authentication, report management, claim verification, notifications, and real time updates. If a real MongoDB database is not available, make sure it still runs with a fallback so I can test it easily.

Use the existing project structure, and if you need current docs for any library details, look them up online. Also include a couple of demo accounts so I can sign in and try it right away.
