/*
   Aportes de GM TECHNO, dentro del portal gmtechno.com.ar.
   Usa el mismo sistema visual que el portal: la paleta del manual (índigo y
   cielo), el crema de fondo, Jost para todo el texto y JetBrains Mono para
   los rótulos del estilo «// talleres». El encabezado y el pie son copia del
   portal: si el portal cambia, se cambian acá también.
   Todos los pares de texto y fondo pasan 4,5:1.
