  DESIGN TOKENS — Manual de Microbiología
  Mismo sistema (tipografía, espaciado, arquitectura de sitio) que el resto
  de la colección, con paleta propia: acento oliva de laboratorio
  ("agar" — el tono cálido y terroso de un medio de cultivo, distinto de
  cualquier verde, ámbar o violeta ya usado en la colección) sobre un papel
  color pergamino/agar cálido, y una escala semántica de callouts que no
  repite ningún hex del resto de la colección.
