- No oversaturated accent colors (saturation cap: 80%)
- No 3-column equal-width feature layouts — use zig-zag or asymmetric grid
- No `h-screen` — use `min-h-[100dvh]`
- No AI copywriting clichés: "Elevate", "Seamless", "Unleash", "Next-Gen"
- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos

1. Siga fielmente o estilo visual determinado.
2. Use ícones SVG inline de alta qualidade (estilo Heroicons ou Lucide) — PROIBIDO usar emojis como ícones.
3. Adicione `cursor-pointer` e estados de `hover` suaves (transition-all) em todos os elementos interativos.
4. Estrutura Obrigatória da Página:
   - Navbar (Logo + Links + CTA)

   - Footer completo com redes sociais, política de privacidade, termos de uso, contato e links SEO.
5. Todo o conteúdo textual deve ser em Português Brasileiro (PT-BR).
