 * Ensure cloned navigation links inside the mobile menu remain visible.

 * When the JavaScript clones this element into the mobile menu, the
 * cloned element inherits `display: none`, resulting in an empty
 * dropdown. We reset the display property here and arrange the links
 * vertically to build a proper mobile menu. We also add a small gap
 * between items and make each link occupy its own row for better
 * tapping targets.
