/*
 * Guest Order Access 2.0 (§11.2) — standalone stylesheet for /guest-orders.html.
 *
 * Kept out of css/shop-page.css on purpose: the shop page is the highest-traffic
 * surface in the repo and every rule there is a regression risk for the
 * authenticated storefront. This file only ever matches body.guest-orders-page.
 *
 * Layout follows 独角发卡 frontend/user/src/views/GuestOrders.vue block for
 * block (header / saved-auth hint / 4-column query form / tip / alert / empty
 * state / order cards / pagination), re-implemented in plain HTML+JS because
 * this site is server-rendered markup, not Vue.
