/* ═══════════════════════════════════════════════════════════════════════════
   HEXTECH IA — LANDING PAGE (landing.css)
   ═══════════════════════════════════════════════════════════════════════════

   CAMADA 3: estilos EXCLUSIVOS da landing. Tudo que for genérico vive
   em hextech-ui.css — se você precisar de algo daqui em outro app,
   promova a classe para lá.

   ESTRUTURA DA PÁGINA (na ordem do DOM):
   .lp-nav        → barra fixa de navegação (vidro)
   .lp-hero       → dobra principal: headline + núcleo de cristal
   .lp-problem    → a dor do jogador (cartões vermelhos/neutros)
   .lp-solution   → as 3 fases (antes/durante/depois)
   .lp-features   → grade de 6 recursos + banner compliance
   .lp-brain      → diagrama animado do motor de inteligência
   .lp-why        → comparação "overlay genérico vs Hextech"
   .lp-final      → CTA de fechamento cinematográfico
   .lp-footer     → rodapé + disclaimer Riot
