/**
 * Routes `/review-order/{id}/?key={order_key}` to the WooCommerce-managed
 * Review Order page and renders the read-only landing page through the
 * `[woocommerce_review_order]` shortcode.
 *
 * The page is intentionally hosted outside the checkout/my-account family:
 *
 * - It is not a checkout sub-mode like order-pay or order-received; the
 *   customer is reviewing past purchases, not transacting.
 * - It is not a my-account endpoint because the order key is the auth, so
 *   guest customers must be able to reach it without logging in.
 *
 * The route uses the same wp_posts-backed page pattern as the checkout
 * page so the active theme owns the page chrome (header, footer, sidebar)
 * on both classic and block themes; the shortcode only renders the form
 * body inside `the_content`. Any failed gating check renders the theme's
 * 404 template so a leaked or stale link cannot disclose order existence.
 *
 * The container auto-calls `init()` after instantiation, which is where
 * the WordPress hooks are registered. Resolution is driven by the
 * `OrderReviews` wrapper that lists this class as an `init()` argument.
 *
 * @internal Just for internal use.
