   Conceito: central de operações forjada em metal — a paleta parte do
   contraste entre o âmbar de metal em brasa (ação, força, "Titan"
   forjado) e o azul-aço frio (dado, controle, precisão). Tipografia
   condensada e em caixa alta nos títulos remete a placas industriais
   e painéis técnicos; a fonte monoespaçada em números e badges dá a
   leitura de "painel de instrumentos" pedida no briefing original.
