NovaNoir/Vance-pettycash — reverse-engineered prompt

Build me a simple petty cash manager web app for a small team.

I want to be able to see how much cash is available, add money when the fund is topped up, and record small expenses with a date, amount, person, category, and short note. The app should show a clear running balance, a recent transaction list, and simple totals so it’s easy to understand where the money went.

Make it feel clean and modern, like a lightweight dashboard, with forms that are easy for a non technical person to use. Include basic validation so people can’t save empty or invalid entries. It should work well on desktop and mobile.

Please build it as a polished Next.js TypeScript app using the existing style setup in this project. If you need current docs for the UI tools or deployment setup, look them up online.
