/* Lumeli design system: componentes na linguagem do apple.com (DESIGN.md, com as medidas de 11/10/2026). Só tokens,
   nenhuma cor literal. Regras da casa:
   - cantos: 6px item de menu; 12px campos, opções, menus e avisos; 18px cartões; pílula botões e chips;
   - bordas: cartão sem borda (sombra suave); campo e opção com #86868b; divisória #d2d2d7; botão secundário com contorno de texto;
   - texto: tamanho, espaçamento e entrelinha andam juntos (--font-size-X com --tracking-X e --leading-X);
   - cor: --color-primary preenche, --color-link escreve; estado só em texto colorido.
   Ordem: base, casca, página, cartões, botões, campos, seleção, listas e estado, gráficos, conversa, documentos,
   administração, telas pequenas, preferências do sistema. */
