/**
 * OREM Referencias de domicilio block — frontend styles.
 *
 * DOM model (verified live on staging via browser DOM inspection)
 * ---------------------------------------------------------------
 * The server emits a placeholder:
 *     <div data-block-name="orem/referencias-domicilio"
 *          class="wp-block-orem-referencias-domicilio"></div>
 * WC Blocks' inner-block hydrator CONSUMES that placeholder when it
 * mounts our React component. After hydration, the DOM has only the
 * React component's output:
 *     <div class="orem-referencias-domicilio is-collapsed|is-expanded">
 *       ...
 *     </div>
 * Therefore CSS selectors must target `.orem-referencias-domicilio`,
 * NOT `.wp-block-orem-referencias-domicilio` (a previous version did
 * the latter — dead code, removed).
 *
 * Final position after JS move (see checkout.js::initReferenciasIn
 * ShippingGroup) — INSIDE the shipping fieldset's step-content:
 *
 *   .wp-block-woocommerce-checkout-shipping-address-block
 *     └── .wc-block-components-checkout-step__content
 *           ├── .wc-block-components-notices
 *           ├── .wc-block-components-notices__snackbar
 *           ├── .wc-block-components-address-address-wrapper
 *           │     └── .wc-block-components-address-card-wrapper
 *           │           └── .wc-block-components-address-card  ← visible card
 *           ├── .orem-referencias-domicilio  ← us
 *           └── .wc-block-checkout__use-address-for-billing
 *
 * Visual nesting via :has()
 * -------------------------
 * Our block is NOT a direct sibling of `.wc-block-components-address-
 * card` (different depths). We strip the card's bottom border via the
 * grandparent path: target `.wc-block-components-address-address-
 * wrapper` when it has a `.orem-referencias-domicilio` sibling, then
 * cascade into the card to remove its bottom radius/border. ~92%
 * browser support for `:has()` as of 2026; older browsers see two
 * separate panels (graceful degradation, fully functional).
 */

/* ------------------------------------------------------------------ *
 * 1) Show/hide based on shipping address mode.
 *
 * WC Blocks toggles between "summary" mode (showing the saved address
 * card with an Editar link) and "edit" mode (showing the address form
 * fields) by adding/removing the `.is-editing` class on
 * `.wc-block-components-address-address-wrapper`. Verified live on
 * staging via browser DOM inspection:
 *
 *   Summary mode (collapsed):
 *     <div class="wc-block-components-address-address-wrapper">
 *
 *   Edit mode (expanded, after clicking Editar):
 *     <div class="wc-block-components-address-address-wrapper
 *                 is-editing is-animated">
 *
 * Referencias de domicilio is a piece of ADDRESS DETAIL. It belongs
 * with the form when the customer is actively typing their address —
 * not with the summary card when they're just reviewing it. So:
 *   - Default: hidden
 *   - Visible only when the address-wrapper carries .is-editing
 *
 * Our block is a sibling of `.wc-block-components-address-address-
 * wrapper` (both inside `.wc-block-components-checkout-step__content`),
 * so the general-sibling `~` selector hits cleanly.

 * 2) Visual treatment when shown (edit mode).
 *
 * In edit mode, the address form-wrapper is showing the input fields.
 * Our block sits below those fields. We render as a quiet card with a
 * subtle border so it reads as "additional address info" rather than
 * a separate checkout step.
