   manual.css — CSS do Manual de Uso

   Ficheiro partilhado por dois sítios: a página "Manual de Uso" dentro do painel
   (index.html) e a página pública manual.html. Estava embutido no <style> do
   index.html; foi extraído para aqui quando o manual passou a ter uma versão
   pública, para não haver duas cópias a divergir.

   Depende das variáveis de cor (--line, --ink, --blue, --muted, --faint), que
   cada página define no seu próprio :root.
