/* Portal Aftosa — identidad "panel de instrumento de vigilancia sanitaria animal".
   Superficie fría de gabinete de laboratorio + un único sistema de semáforo de estado
   (verificado / en observación / alerta / neutro) reutilizado en badges, indicador de mapa
   y lectura de sincronización — en vez de un acento decorativo suelto. Sin serif, sin crema,
   sin negro+neón, sin grilla de diario: superficies con aire, radios suaves, tipografía técnica
   (familia IBM Plex completa). */
