Abdoubel26/trustfall ? reverse-engineered prompt

Build me a simple but polished web app that lets people explore the Prisoner’s Dilemma in an interactive way.

I want the main page to explain the game in plain language, then let users choose between cooperate and betray for each round, see the outcomes, and understand how the payoff changes over time. It should feel like a small simulator where I can try different strategies, run repeated rounds, and compare what happens when both players are nice, both are selfish, or one switches behavior. Make it visual and easy to use, with clear results, a short explanation of the rules, and a nice modern look that works well on desktop and mobile.

If it helps, use current Next.js guidance and look up anything you need online. Keep the experience smooth, interactive, and educational, so someone who has never heard of game theory can still play around and learn from it.
