/*
  DESIGN TOKENS — Manual de Epidemiología
  Mismo sistema (tipografía, espaciado, arquitectura de sitio) que el resto
  de la colección, con paleta propia: acento "azul epidemiológico" (el
  cobalto/prusia de los mapas de brotes y los tableros de vigilancia, en
  homenaje al mapa del cólera de John Snow), sobre un papel gris-azulado
  frío ("papel de sala de situación"), y una escala semántica de callouts
  que no repite ningún hex del resto de la colección.
