/* Kairotick / TradeWarden site system (2026-10-07, v3). One idea carries the identity: your firm draws the red line,
   TradeWarden draws the yellow one. Red dashed = a firm's limit, solid yellow = where TradeWarden acts; nothing else uses
   those two colours. Type: Archivo only, wide for words that lead, narrow for numbers. Built by Alireza. */
