kkanitin/StackVest ? reverse-engineered prompt

Build me a personal investment tracking dashboard for learning and practice, something clean and simple that helps me see my portfolio at a glance.

I want users to be able to sign in with Google, add and view assets, and see a visual breakdown of how everything is spread out in the portfolio. The main screen should feel polished and easy to understand, with a heat map style view for portfolio health and allocation. I also want a DCA simulator where I can plug in a contribution amount and time period, then see a rough future growth estimate in a nice visual way.

Please make it as a small full stack app with a React frontend and a Go backend, and keep the code organized so it is easy to learn from. If you need current docs or setup details, look them up online. Keep the app focused on personal use, non commercial, and make sure the UI feels modern and lightweight.
