   projetodxn.com — tokens de color y base
   =========================================================================
   Paleta: colores de la BANDERA DE BRASIL, no los de DXN (decisión
   explícita del usuario, para diferenciarse tanto de DXN como del sitio
   hermano de Perú, proyectodxn.com).

   Hex verificados contra archivos oficiales del gobierno brasileño (no hay
   ley que fije el tono exacto, pero estos son los valores que el propio
   gobierno publica y los que se usan como referencia estándar):
     - Verde:    #009440
     - Amarillo: #ffcb00
     - Azul:     #302681
   Fuente: https://en.wikipedia.org/wiki/Flag_of_Brazil (sección de color).

   El resto de la arquitectura (radios, tipografía, estructura de tokens)
   sigue el mismo método que proyectodxn.com para reusar el criterio ya
   probado — lo que cambia es la paleta, no el sistema.
