Ensure that the nav bar, with all navigation items and the locale switcher,
remains intact and unchanged when scrolling down past the site header, which
causes the bar to become fixed at the top.

This also changes the layout of the nav bar on narrow screens so that the
locale switcher and the menu toggle button are on separate rows, with the
switcher first, allowing the toggled menu items to expand beneath.
