/* Sistema de design "Papel & Tinta".
   Regras da casa:
   1. Papel claro por padrão. O escuro é uma sala, não o padrão.
   2. Estrutura vem de fios de 1px e alinhamento — não de caixas com sombra.
   3. A tipografia carrega o peso. Serifa só onde há intenção editorial.
   4. Cor é sinal, nunca enfeite.
   5. Movimento é físico e ligado ao scroll. Nada flutua por decoração. */
