   Design System v4 "Terra Noturna"

   A Terra (v3) foi para o escuro: papel vira grafite quente, o marrom
   sela vira cobre aceso. Fraunces continua dando a voz editorial,
   Inter segura a leitura e JetBrains Mono marca tudo o que é técnico.
   Profundidade vem de camadas, perspectiva e luz, nunca de enfeite:
   o brilho é sempre de uma fonte (o mouse, o cobre), nunca aleatório.
