   ChocoUnique — sistema de design

   A paleta vem da vagem de cacau, não da estética "artesanal" de papel kraft:
   casca carmim, polpa rosada, tinta de cacau torrado.

   Uma só família tipográfica (Archivo variável), com a LARGURA como eixo
   expressivo — é assim que funciona a letra em embalagem. O logótipo fica a
   ser a única voz com serifa, e por isso lê-se como marca em vez de competir.
