How I Built It

I built this app only by using Google Antigravity agent manager without touching the IDE. Firstly, I prompt the entire requirements down and just let the agent to create the implementation plan. I review the implementation plan and refine some stuff, and let the agent continue with the coding process. After the coding process was done, the agent by himself test the application and make sure there are no errors.
