/* ==========================================================================
   LMglass — camada de movimento e microinterações
   Princípios:
   • anima só transform/opacity (sem layout → sem CLS);
   • todo movimento fica dentro de @media (prefers-reduced-motion: no-preference);
     com "reduzir movimento" o conteúdo aparece direto, sem hover animado nem paralaxe;
   • sem JS o conteúdo continua 100% visível (estados ocultos só com html.js-ready);
   • animações com fill-mode "backwards": não prendem estilos depois de terminar.
