/* ============================================================
   AZIMUTE VIRTUAL — Sistema de Design
   Conceito: o logótipo real é um hub de rede — um nó central
   ligado a seis nós satélite. É a metáfora perfeita, já pronta,
   para uma empresa de sistemas informáticos: infraestrutura
   interligada, monitorizada em permanência a partir de um centro
   de controlo. Toda a identidade deriva desta forma: nós, ligações,
   sinal a percorrer a rede.
   Paleta extraída diretamente do logótipo oficial.
