 ÍNDICE DE SEÇÕES:
 1. CONFIGURAÇÕES GLOBAIS E VARIÁVEIS (A base do design)
 2. ESTILOS DE BASE E RESET (Garante consistência entre navegadores)
 3. CLASSES UTILITÁRIAS (Componentes reutilizáveis como .btn, .container)
 4. LAYOUT PRINCIPAL (Header, Footer - A estrutura da página)
 5. COMPONENTES (Partes específicas da UI: Hero, Cards, Pesquisa, etc.)
 6. MEDIA QUERIES (Toda a lógica de responsividade)
