   Reset de estilos de Materialize en <nav>
   
   MOTIVO: Materialize aplica estilos globales a <nav>:
   - background-color: #ee6e73
   - box-shadow: 0 2px 2px 0 rgba(0,0,0,.14)...
   - color: #fff
   - width: 100%
   - height: 56px / line-height: 56px
   
   Usamos `unset` para neutralizar estos estilos
   heredados SIN afectar otros <nav> del sitio.
   Solo aplica dentro del scope .blog-nav-bar.
   =========================================== */
