   -------------------------------------------------------------------------
   Paleta "aço + sinal de leitura": nada de creme/terracota nem preto/neon
   genéricos. O produto vive em dois contextos: um totem fixo perto de uma
   porta (device.html, tema escuro, alto contraste, legível de longe) e
   painéis de gestão (claro, denso, para uso prolongado em escritório).

   Assinatura visual: o "retículo de leitura" — cantos de mira em L que
   emolduram a câmera/estado de processamento — reaparece em toda a suíte
   como o motivo de "capturando/validando".
