/* ============================================================================
   FAIRCO · sistema de desenho — O CONVITE GRAVADO
   O salão é verde-garrafa; o convite é champanhe com filete duplo de ouro.
   A marca principal é a DISCRIÇÃO: a agenda não se publica, os nomes não
   circulam, e o site inteiro fala na voz de quem convida — nunca de quem
   anuncia. Régua da casa: corpo justificado, títulos com balance, 390 primeiro.
   Faces: Libre Caslon (a gravura), Karla (a conversa).
