/*
  TOKENS DE DISEÑO — Home comercial de AI Landscape Designer
  -------------------------------------------------------------
  Identidad DISTINTA del workspace (que sigue oscuro/técnico, en /app).
  Acá: editorial, cálido, "architecture + interior design magazine", no
  "AI startup" — sin negro-neón, sin gradientes excesivos, sin stock photos
  genéricas. Misma marca (el ícono de mira/compás), mismo verde salvia como
  hilo conductor entre las dos identidades, pero sobre paleta clara.
