/*
  DESIGN TOKENS — Manual de Genética
  Mismo sistema (tipografía, espaciado, arquitectura de sitio) que el resto
  de la colección, con paleta propia: acento ciruela/violeta "cromosómico"
  (el tono de una tinción de bandas G en un cariotipo, o de un cromosoma
  duplicado en metafase) sobre un papel frío con velo lavanda apenas
  perceptible — distinto del cerúleo de Inmunología, el violeta-azulado de
  Biofísica y el magenta H&E de Histología — y una escala semántica de
  callouts que no repite ningún hex del resto de la colección.
