Cowles-Quantitative-Corporation/Oryntra ? reverse-engineered prompt

Build me Oryntra, a private first market research app for stocks that helps me scan the market, inspect historical behavior, and compare simple trading ideas in a clear and honest way.

I want a clean research workspace with sign in, a public scanner, and a private account area where I can see derived analysis, pattern observations, risk metrics, and plain language explanations of what the data suggests. It should feel like a serious quant research tool, not a trading app, so please do not include brokerage connections, order placement, or any kind of live trading.

Use the server side to handle market data retrieval, local caching, analysis, and structured outputs, and make the front end responsive and easy to browse on desktop and iPhone. Include chart views, search for tickers, strategy comparison, portfolio style diagnostics, and a simple way to explain why a signal is showing up.

If you need to, look up current docs online while building it, but keep the app focused on transparent research and clear limits, not predictions or investment advice.
