/* Landing de shuggi.app (Sprint LP-1). Paleta y tipografía del manual de marca AMP v1.
   Contraste WCAG medido (ver build.py y el plan): verde texto #3F6B3B con blanco 6.22 y sobre
   crema 6.06; sobre brote 4.60. Bosque #5E9257 y hoja #8AC06B nunca llevan texto de cuerpo.
   Azul marino #2D4373 solo en el punto: es el único acento que no es verde. Oscuro sobre el navy
   de las versiones oscuras de AMP (#1B2A44). */
