/* Infinity Ventiladores – página inicial futurista (views/home.ejs + /static/js/home.js)
   Carregada só na home, depois de site.css, future.css e dos CSS dos componentes
   (tech-ui, airflow, circular-carousel). Tema escuro "tech premium":
   chão navy profundo, linhas finas, azul → ciano do logotipo e dourado discreto.
   Regras do cliente: fotos reais intocadas (nenhum filtro de cor; só sombra e brilho ATRÁS do produto);
   decoração abstrata (anéis, grade, pontos); animações pausam fora da tela/aba oculta (home.js e
   componentes) e somem com prefers-reduced-motion (site.css zera animações e transições). */
