   Paleta "Bancada": fundo quase preto esverdeado e um único verde-lima, a cor
   de LED e de placa de circuito. O lima é só destaque e fundo de botão (texto
   escuro por cima). Texto em lima só aparece sobre o fundo escuro; no bloco
   claro o destaque vira --lime-ink, que passa AA sobre --paper.
