   Brand: azul profundo / azul sereno / off-white neutro

   Este arquivo usa variáveis (custom properties) para que o
   Modo Escuro seja uma paleta pensada especificamente para o
   tema — não uma simples inversão de cores. Os tokens de marca
   (--brand-*) são constantes; os tokens semânticos (--heading,
   --ink, --surface, --page-bg, etc.) mudam de valor conforme o
   tema ativo.
