     GHDARU TECNOLOGIA — direção C ("o modelo"), aprovada 2026-08-14
     Paleta derivada do logotipo. Contraste medido, não estimado:
     ver perfil/kit-de-marca.md.

     A regra que governa tudo: o ciano da marca reprova como texto
     sobre branco (1.97:1) e é excelente sobre escuro (8.45:1).
     Por isso o degradê vive no gráfico e nas faixas escuras.
     Tema único, deliberado — a página pinta todas as suas cores.
