samidor/futures-levels ? reverse-engineered prompt

Build me a clean static dashboard for daily futures key levels that shows support and resistance for ES, NQ, CL, and GC.

I want one main page that makes it easy to jump into each market, plus separate report pages for things like key levels, options flow, open interest changes, max pain, volume GEX, volatility skew, term structure, unusual volume, and strategy summary. The dashboard should present the numbers in a simple, readable way, with charts or tables where helpful, and make it obvious which levels are the most important for today.

Use the existing data files in the repo to power the pages, and keep everything working as a GitHub Pages style static site. If you need to look up current docs or best practices for the charting or layout, go ahead. Also include a basic login page if that fits the current site flow, but keep the whole thing fast, polished, and easy to scan on desktop and mobile.
