   Ópera de Morelia — Nav adaptado del estilo Apple
   - position: sticky (no fixed) — la barra está arriba del contenido, no encima
   - Bg unificado entre nav y flyout (mismo color exacto) = sensación de panel único
   - Backdrop con blur del contenido detrás cuando el flyout abre
   - Alto 52px (adaptado a Ópera de Morelia, no los 44 de Apple)
   - Container al ancho del sitio (--max = 1320px)
   - CTA primario en GOLD (#BDB09D) — paleta de marca
