/* Zavra · sistema visual único (direção Horizonte)
   A marca é sóbria: tinta, papel e Instrument Sans. A cor vem dos campos fotográficos desfocados (céu, brasa, mar, mata,
   aurora, horizonte), que aparecem como fundos vivos e, em doses pequenas, como acento de cada tema.
   Seções escuras são o padrão; .light troca as variáveis e o mesmo componente funciona sobre o papel.

   Regras de consistência
   - Tipos: display, h2, h3, lead, corpo, sm, xs. Nada fora desta escala.
   - Raios: 4px nos degraus (forma da marca), 16px em painéis e cartões, 999px em botões e etiquetas.
   - Espaço: --sec-y entre seções, 48–64px entre título e conteúdo, 12/16/24px dentro dos componentes.
   - Cores por tema, usadas no site inteiro: Ontologia = céu, Agentes = brasa, Cockpits = mar, Painéis = mata, Controle = aurora. */
