   RE/MAX Casabella · header
   Réplica da mecânica do fineprop.com: header branco de 110px com barra
   utilitária acima do menu; ao rolar 10px vira fixo, ganha sombra, encolhe
   o logo (scale .8) e esconde a barra utilitária. Menu mobile desliza da
   direita com blur, itens entram com navAnimate.
