/* ==========================================================================
   AE CONNECT — Design System v3
   --------------------------------------------------------------------------
   Rebuild of the .aec-v2 system with:
     • CSS custom properties  — change a colour in ONE place, whole site updates
     • Manrope typography     — matches the Elementor global font
     • Fluid type via clamp() — scales smoothly, no jumps between breakpoints
     • WCAG AA colour palette — every text/background pair tested
     • 6 breakpoints          — matches the Elementor breakpoints already set
     • aspect-ratio images    — no distortion on any screen

   INSTALL
     1. Upload to /wp-content/themes/netlink-child/assets/aec-v3.css
     2. Add to netlink-child/functions.php:

        add_action( 'wp_enqueue_scripts', function () {
            wp_enqueue_style(
                'aec-v3',
                get_stylesheet_directory_uri() . '/assets/aec-v3.css',
                array(),
                '3.0.0'
            );
        }, 99 );

     3. Remove the inline <style> blocks from the 7 pages using aec-v2.

   USAGE
     Wrap page markup in <div class="aec-v3"> … </div>
     The v2 class names still work — v3 is a drop-in replacement.
