WooCommerce core does not provide AJAX add-to-cart on the single product page or for variable products listed on archive pages (it redirects to the single view). This plugin adds an unobtrusive AJAX workflow for:
<ul>
<li>Simple products (single product page button becomes AJAX)</li>
<li>Variable products on archive & block-based Product Collection (opens an accessible modal to choose attributes, then adds via AJAX)</li>
<li>Classic themes and modern block/FSE themes (2025 and later) with Product Collection blocks</li>
</ul>
Highlights: 
* Works with WooCommerce fragments (mini-cart updates automatically) 
* Accessible modal (focus trap, ESC to close, restore focus) 
* Nonce-secured AJAX endpoints; sanitized and validated input 
* Settings page to enable/disable variable product archive functionality 
* Block theme compatibility (intercepts “Select options” buttons) with slug/product_id fallback 
* Performance-minded (loads minified bundles built via Webpack; falls back to source if missing) 
* Translations auto-loaded from WordPress.org (no manual POT/PO generation required)
Privacy: This plugin does not send any data to external services. It only uses WooCommerce cart/session APIs.
<h3>Development</h3>
Build commands:
<ol>
<li>Install dependencies: 
npm install</li>
<li>Production build (minified + source maps): 
npm run build</li>
<li>Watch during development: 
npm run watch</li>
<li>Lint JS: 
npm run lint</li>
</ol>
Translations: WordPress.org language packs auto-load this plugin’s strings. The former POT/PO/MO tooling and i18n loader file were removed (WP 4.6+). Do not add a load_plugin_textdomain() call; simply keep the Text Domain header accurate.
