/**
 * Accessible Navigation Styles
 *
 * Functional defaults for the W3C ARIA disclosure navigation pattern.
 * Adapt colors, spacing, and breakpoints in your child theme to match
 * the host theme's design — these are not finished designs.
 *
 * Note: visibility of submenus is controlled by the [hidden] attribute
 * via JavaScript. Do not override [hidden] with display rules — doing
 * so will break the toggle behavior.
