/* ==========================================================================
   DURATEC PAN — site institucional (overhaul visual v2)
   Paleta extraída da foto da fábrica (assets/images/hero-bg.png):
     base carvão quente, azul cobalto das esteiras, luz âmbar dos refletores.
   Regra de cor: azul = acentos estruturais (números, labels, bordas ativas);
   âmbar = somente conversão (CTA WhatsApp e chip Especialidade).
   Raios: pílulas glass = full, botões 12px, painéis e pranchas 18px, FAB circular.
   Liquid glass: aproximação web (backdrop-filter + bordas em camadas),
   com fallback sólido para prefers-reduced-transparency.
