sergeabchiyt-cyber/Crypto-terminal ? reverse-engineered prompt

Build me a single page BTCUSDT crypto terminal that runs entirely in the browser from one HTML file, with no server, no login, and no install.

I want a live depth ladder that combines order book size from multiple exchanges into one view, with bids in green, asks in red, a spread divider in the middle, and clear highlighting for big walls and the current price area. It should also show a live trade tape underneath or beside it, color coded by exchange so I can tell where each trade came from.

Use Binance as the main reference feed for the book, and connect to as many public exchange WebSocket feeds as you can for the rest. The page should reconnect automatically if a feed drops, keep the UI smooth, and only redraw when needed so it stays fast. Let me change the tick size from the page itself, and show connection status and how many feeds are active. If you need to look up current exchange docs online, do that.
