   Barra de progresso, aderência de segmento, confiança da leitura e os

   O valor entra por --fill (0 a 1) e é aplicado com scaleX, não com width:
   escala roda no compositor, enquanto largura recalcula layout a cada quadro.
   Sem JavaScript o medidor já aparece cheio no valor certo — a animação é
   acréscimo, nunca condição para o dado aparecer.
