/*
  DESIGN TOKENS — Manual de Semiología
  Mismo sistema (tipografía, espaciado, arquitectura de sitio) que el resto
  de la colección, con paleta propia: acento "acero clínico" (el gris-azulado
  frío y metálico de un estetoscopio y el instrumental de examen físico),
  sobre un papel color "camilla" (el blanco-hueso cálido del papel de
  examen), y una escala semántica de callouts que no repite ningún hex del
  resto de la colección.
