/* ---------------------------------------------------------------
   Impressão / exportar para PDF
   Duas coisas quebram o fundo no PDF e as duas são tratadas aqui:
   1. o navegador descarta cores de fundo na impressão, a menos que
      print-color-adjust mande o contrário;
   2. a faixa de margem do @page nunca é pintada — por isso ela vai
      a zero e o respiro vira padding do conteúdo.
   O Chromium força prefers-color-scheme: light ao imprimir, então a
   paleta escura é fixada aqui na mão em vez de vir da media query.
