liquiditymapperfast/liquiditymapperfast.github.io ? reverse-engineered prompt

Build me a browser based market map for BTC that shows a live liquidity heatmap, order book ladder, price profile, depth, open interest, and footprint style volume candles.

It should work with no sign up and run entirely in the browser on a static host, reading public exchange feeds directly from the user’s machine. If there’s a local server mode, that can add recorded history and replay, but the main experience should still work without it. I want a clean charting workbench where I can zoom, pan, jump to a time, and replay past market action from a chosen point. Include venue selection for the major exchanges, save my layout and settings in the browser, and make the page feel like a real trading terminal with a right side profile column and a row for open interest.

Please also make it easy to understand with a guide button or help section, and keep it focused on BTC first, with the option to support a few other major coins too.
