   Cefas Rádio Web — design tokens
   Conceito: "dial de sintonia" sobre pedra. Menu fixo no topo, rodapé fixo
   com redes sociais e play central, fundo com foto desfocada (multidão
   de mãos levantadas) para dar profundidade e clima de adoração.
   Paleta: preto & branco monocromático, moderno — mesma linguagem da logo
   Cefas (pedra rachada em preto/branco). Sem dourado, sem ferrugem.
   Layout pensado para caber 100% na tela (sem rolagem) em qualquer altura.
