* Provides attribute sanitization, WooCommerce query building, product-card |
| 6 |
* markup rendering, and a hardened add-to-cart AJAX endpoint |
| 7 |
* (`bb_wpg_add_to_cart`) used by the frontend `view.js` for simple products. |
| 8 |
* |
| 9 |
* Security model for `bb_wpg_add_to_cart`: |
| 10 |
* - Nonce verified on every request via check_ajax_referer(). |
| 11 |
* - product_id sanitized with absint() and validated against wc_get_product(). |
| 12 |
* - Only purchasable, in-stock, simple/non-variable products are added. |
| 13 |
* - All responses use wp_send_json_success / wp_send_json_error. |
| 14 |
* |
| 15 |
* All card output is escaped (esc_html / esc_url / esc_attr / wp_kses_post). |
