/*
 * Paula · Medicina Tradicional Chinesa — demo (v3, conceito "Meridiano").
 * Uma linha fina percorre a coluna de leitura como um canal de acupunctura;
 * cada secção é um ponto (anel + centro cinábrio) nesse meridiano, que se
 * desenha no carregamento. Tudo serif, quente e íntimo: Fraunces para as vozes
 * grandes, Newsreader para leitura. Papel aveia, tinta castanha, um único acento
 * cinábrio (o vermelho do selo) reservado aos pontos. Sem mono, sem numeração de
 * secção, sem eyebrows em maiúsculas, sem o truque da palavra colorida. Restraint.
