/**
 * 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. `"@boboko/core": "file:../boboko-core"` as an npm dependency (see this
 *      package's own package.json `exports`), with a bind-mount of the core
 *      checkout into the host's Vite container so the `file:` symlink
 *      resolves in dev (see 3dealer's docker-compose.core-dev.yml) and
 *      `resolve.preserveSymlinks: true` in the host's vite.config.js so bare
 *      imports (stimulus, leaflet) still resolve against the host's own
 *      node_modules through that symlink.
 *   2. `import { registerCheckout } from '@boboko/core/checkout'` in the
 *      host's own JS entry point, and a @vite entry for
 *      `node_modules/@boboko/core/resources/css/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.
