/* Chipnomics — estilos del sitio.
   Identidad "chip": fondo casi negro, un solo acento ámbar, esquinas cortadas en diagonal
   (como un chip), contactos cuadrados, cables de circuito y textos chicos en letra de máquina.
   Sin curvas en la interfaz: el único elemento redondeado es el logo.
   El sitio no permite estilos en línea (seguridad), así que todo el diseño vive acá. */
