   Organização do arquivo:
     1. Tokens de design (cores, raios, sombras, gradientes)
     2. Reset e base
     3. Layout (container, seções, cabeçalho de seção)
     4. Componentes de navegação (topbar, header, menu, breadcrumb, rodapé)
     5. Componentes de conteúdo (hero, cards, planos, passos, tabelas, FAQ…)
     6. Utilitários e responsivo
   Todas as cores usam oklch, herdadas do design system original.
