/**
 * Navrail Navigation — structural & behavioral styles.
 *
 * Mirrors the structural patterns already established in navrail-toc.css
 * (flex rail, hidden-but-functional scrollbar, RTL-safe edge fade,
 * accessible focus ring, reduced-motion) under its own `.navrail-nav`
 * namespace, so it never collides with `.htoc*` selectors and the two
 * widgets can be styled completely independently. Colors/spacing that a
 * user configures via the Style tab are injected by Elementor itself; this
 * file only contains the rules the widget needs to function correctly.
