   A família da Política e do Vanguard: abertura preta com a ficha em mono,
   display em peso 500 alinhado à esquerda, a régua como placa fumê pousada na

   pé do hero que pulsa uma vez a cada poucos segundos ("um batimento
   silencioso", do manifesto). O manifesto tem palco próprio e acende palavra
   a palavra com a leitura. Faixas alternam preto e papel.
   Um movimento por faixa; o resto só no gesto. Prefixo .sob-
