Real XAU/USD read via COMEX Gold futures (GC=F, Yahoo Finance's public feed — unofficial, no API key). Futures and spot gold are tightly arbitraged, so this is a materially more accurate real gold price than the PAXGUSDT (tokenized gold) proxy Gold Mode uses elsewhere in this app. Unlike crypto, gold futures don't trade a true 24/7 session — outside real market hours you're looking at the last real close, not a live quote.
