Análise e Correção do main.js
Vou otimizar completamente o arquivo main.js com melhorias em performance, acessibilidade, segurança e boas práticas.

📋 Principais Problemas Identificados
Event listeners duplicados - mesma funcionalidade repetida
Falta de debounce/throttle em eventos de scroll
querySelector repetitivo - sem cache de elementos
Falta de validação robusta
Código não modular - tudo em um único escopo
Falta de tratamento de erros
Animações sem consideração para prefers-reduced-motion
Prefetch agressivo sem estratégia
IntersectionObserver duplicado
Scroll spy mal implementado
✅ main.js OTIMIZADO E CORRIGIDO
