/* ============================================================
   DESIGN TOKENS
   Aesthetic: trading-desk instrument panel. Near-black charcoal
   base (not pure black -- pure black makes data feel like a void).
   Long/short color coding borrowed from real exchange tickers
   (green=long/profit, red=short/loss) because that vocabulary is
   load-bearing for a trading tool, not decorative. A single amber
   accent marks anything that needs the operator's attention (live
   state, warnings, the kill switch). Monospace for every number so
   columns of price/PnL data align like a real ticker tape.
