🚀 DESPLIEGUE Y PRODUCCIÓN — TRADING TERMINAL

⚠️ REGLA FUNDAMENTAL: TESTNET ANTES DE PRODUCCIÓN

DESARROLLO    → localhost + Binance Testnet + DB local
STAGING       → Servidor + Binance Testnet + DB real (datos fake)
PRODUCCIÓN    → Servidor + Binance Mainnet + DB real (DINERO REAL)

NUNCA pasar directamente de DESARROLLO a PRODUCCIÓN.
