/**
 * The cart + checkout module — its view/component namespace, its routes,
 * and the composer that feeds the always-present cart drawer. Strings
 * (__('checkout.cart.*')) are NOT wired up here — same as storefront.*
 * elsewhere — they resolve through Lunar's DB-backed translation UI
 * (spatie/laravel-translation-loader), seeded by Checkout\Database\Seeders\
 * CheckoutTranslationsSeeder rather than shipped as lang/ files.
 *
 * A consuming app wires this module in with:
 *   1. `php artisan vendor:publish --tag=core-checkout-assets` — copies
 *      resources/js/checkout/** and resources/css/checkout.css into the
 *      host's own resources/ tree. Vite only ever bundles from a host's
 *      own resources/ directory, so these are published (an explicit,
 *      host-owned, re-publishable copy) rather than imported cross-package.
 *   2. `import { registerCheckout } from './checkout'` in the host's own
 *      JS entry point, and a @vite entry for the published checkout.css.
 *   3. `@include('checkout::drawer')` in the host's own layout.
 * See config/checkout.php for the handful of per-site settings (login
 * route, single-country mode, ...) a host is expected to publish and
 * override.
