/*
  DESIGN TOKENS — Manual de Bioestadística
  Mismo sistema (tipografía, espaciado, arquitectura de sitio) que el resto
  de la colección, con paleta propia: acento azul pizarra ("data blue" —
  el azul frío, sobrio, de gráficos y tablas de datos), sobre un papel
  gris-azulado muy frío casi neutro — distinto del cerúleo saturado de
  Inmunología, del índigo violáceo de Comprensión de Textos y del teal
  verdoso de Biología — y una escala semántica de callouts que no repite
  ningún hex del resto de la colección.
