/**
 * Dirección A · identidad azul petróleo sobre datos en tinta.
 *
 * La regla que gobierna todo este fichero sigue siendo la misma: EL COLOR ES
 * INFORMACIÓN. Lo único que lleva verde / ámbar / rojo es cuánto fiarse de una
 * respuesta, más los estados que piden atención.
 *
 * Lo que cambió respecto a la versión gris: hay un color de marca, y tiene su
 * propio territorio — el cromo (cabecera, lateral, botones, foco, la fila
 * seleccionada). No entra nunca en un dato. Por eso es petróleo y no un azul
 * vivo: convive con las tres bandas de confianza sin pelearse con ellas.
 *
 * Si algún día un porcentaje, un recuento o un tiempo acaba pintado de
 * --brand, la regla se ha roto.
 *
 * Corolario que sobrevive intacto: "verificado" NO lleva color. Que algo esté
 * bien no necesita gritar; solo las excepciones (el juez discrepa, decidió el
 * árbitro) se colorean.
