Shelpid/SETS ? reverse-engineered prompt

Build me a browser based demo of a self evolving trading system that runs entirely in the browser with plain HTML, CSS, and JavaScript, no framework, no login, and no backend.

I want it to simulate a genetic search over simple BTC trading strategies, show each generation evolving, backtesting on historical candle data, then only letting the strategies that pass a basic out of sample check survive into a paper trading leader. The UI should make it feel alive, with a live gene pool, fitness history, a chart of the current strategy, and a small execution log for fills, take profit, stop loss, fees, and balances.

Please include controls to run, pause, step one generation at a time, and change the speed. Let me pass in a seed so the same seed always gives the same result, and support a simple mobile friendly layout. If you need current docs for browser APIs or canvas usage, look them up online.
