/* ═══════════════════════════════════════════════════════════════
   BEE BLACK — sistema visual

   Conceito: a fundação e o que se ergue sobre ela. Desenho de
   engenharia em fios — colunas, travessas, contraventamentos,
   módulos. Construção e sistema, não rede nem partícula.

   O preto não é chapado: varia de temperatura entre seções
   (frio no institucional, quente no trabalho) para dar
   profundidade sem recorrer a degradê.

   Mel é assinatura: aparece em nós de estrutura, na origem de um
   dado e no contato. Nunca como preenchimento.
