   FONTES DE SUBSTITUIÇÃO COM MÉTRICA CASADA
   Enquanto a fonte definitiva carrega, o texto aparece na fonte do
   sistema. Sem ajuste, a troca reflui a página inteira (o famoso
   "pulo" de layout). Os valores abaixo foram MEDIDOS comparando a
   largura e a caixa de linha de cada fonte com a sua substituta:
     size-adjust  = largura real ÷ largura da substituta
     ascent/descent-override = métrica real ÷ size-adjust
   Resultado: a substituta ocupa o mesmo espaço, e a troca é
   imperceptível — sem deslocamento cumulativo de layout.
