## 2. WordPress APIs Used

- Theme support: `add_theme_support('title-tag','post-thumbnails','html5','custom-logo','woocommerce'...)`
- Menus/sidebars/widgets: `register_nav_menus`, `register_sidebar`, `widgets_init`.
- Settings: `register_setting` + single option `xshop_settings` (Settings API).
- Customizer: `customize_register` for preview (typography/colours).
- REST: `register_rest_route` (namespace `xshop/v1`).

## 3. WooCommerce Integration (M2)

- Declared `add_theme_support('woocommerce')` + gallery features (`wc-product-gallery-zoom/lightbox/slider` now disabled via `remove_action` for custom gallery; can re-enable per ADR).
- Wrapper via `woocommerce_before_main_content` / `after_main_content` (`.xshop-main xshop-container .xshop-woo-layout`).
- Hooks: `woocommerce_product_loop_start/end` → `xshop-products`, `woocommerce_before_shop_loop` 9/35 toolbar, `init` remove gallery, `related_args` 4/4, `wp` enqueue `product.js` only on `is_product()`. Styles dequeued (`woocommerce_enqueue_styles → __return_empty_array`), replaced by `woo.css` (global, documented).
- Overrides (4, minimal, versioned): `content-product.php 3.6.0`, `archive-product.php 3.4.0`, `content-single-product.php 3.6.0`, `single-product.php 1.6.4`. See `ARCHITECTURE.md:11` for why/risks. Monitor `WC()->version` and template `Version:` header.

## 4. HPOS

- Uses `wc_get_products` CRUD, not direct post table writes. Compatible with High-Performance Order Storage. No direct `wp_posts` manipulation for orders.

## 5. Elementor

- Widgets registered via `\Elementor\Plugin::instance()->widgets_manager->register` if Elementor active. Namespaced `XShop\Core\Elementor\Widgets\*`. No hard dependency – `is_plugin_active` guard.

## 6. Gutenberg

- Block styles via `register_block_style`, theme.json opt-in later. No classic-editor dependency.

## 7. Multisite

- Not primary target; options are per-site (no network options in v1).

## 8. Upgrade Notes

- Template version bumps checked via `WC template version` comment. Override only where necessary; changelog notes any override update.
