==========================================================
ADA RESPONSIVE NAV — style.css
==========================================================
WHAT IT IS:
An ADA compliant responsive navigation system with
one level of dropdown support and an animated
hamburger menu for mobile.

WHAT IT DOES:
Renders the main site navigation with full keyboard
accessibility, focus management, and ARIA support.
Includes a smooth SVG hamburger animation on mobile.
Dropdowns open on hover (desktop) and tap (mobile).

HOW TO USE:
This file is automatically loaded via the
~common_features/ada_responsive_nav/functions.php
include in the main functions.php file.

The nav HTML is rendered by:
~common_features/ada_responsive_nav/view.php

To customize the visual style for a specific project
add overrides in Section 10 of style.css rather than
editing this file directly.

All values use boilerplate CSS tokens from style.css.
