   Se carga DESPUES de app.css para poder sobrescribir tokens.

   Basado en las recomendaciones de la British Dyslexia Association:
   - Evitar contraste extremo (blanco puro sobre negro puro deslumbra).
   - Fondos crema/pastel; texto oscuro pero NO negro puro.
   - Interlineado >= 1.5, texto grande, espaciado generoso.
   - Linea corta (60-70 caracteres), alineado a la izquierda, sin justificar.
   - Sin cursivas para enfatizar, sin partir palabras con guiones.
