+# Shuffle – Flutter-App
+
+Brettspiel-App für iOS, Android und Web (eine Codebasis). Architektur und Konventionen: `../CLAUDE.md`, `../docs/adr/`.
+
+## Struktur
+
+```
+lib/
+  core/        config, logging, error, result, supabase, routing, l10n, theme
+  features/    <feature>/{data,domain,presentation}
+  l10n/        app_de.arb, app_en.arb (+ generierte AppLocalizations)
+test/          Spiegel von lib/
+env/           *.example.json (echte Umgebungsdateien sind git-ignoriert)
+```
+
+## Starten
+
+```bash
+cd app
+flutter pub get
+cp env/dev.example.json env/dev.json     # Werte anpassen
+dart run build_runner build --delete-conflicting-outputs
+flutter run -d chrome --dart-define-from-file=env/dev.json
+```
+
+Pflichtwerte: `SUPABASE_URL`, `SUPABASE_ANON_KEY` (der Start bricht ohne sie ab).
+Optional mit Platzhalter: `SITE_URL`, `LEGAL_PRIVACY_URL`, `LEGAL_TERMS_URL`, `TERMS_VERSION`, `APP_ENV`.
+
+## Platzhalter-Identität (vor dem Store-Release festlegen)
+
+| Was | Wo ändern |
+|---|---|
+| Bundle-/Application-ID `work.cshomelabs.shuffle` | `android/app/build.gradle.kts` (`namespace`, `applicationId`), Kotlin-Package unter `android/app/src/main/kotlin/`, `ios/Runner.xcodeproj/project.pbxproj` (`PRODUCT_BUNDLE_IDENTIFIER`) |
+| App-Name „Shuffle“ | `android/app/src/main/AndroidManifest.xml`, `ios/Runner/Info.plist`, `web/index.html`, `web/manifest.json`, l10n-Schlüssel `appTitle` |
+| Web-Domain, Rechtstexte, Version der Rechtstexte | `env/*.json` (`SITE_URL`, `LEGAL_*`, `TERMS_VERSION`) |
+
+Die Bundle-ID lässt sich nach der ersten Store-Veröffentlichung nicht mehr ändern.
+
+## Hinweise
+
+- Generierte Dateien (`*.g.dart`, `lib/l10n/app_localizations*.dart`) werden mit eingecheckt; nach Änderungen an `@riverpod`-Code oder ARB-Dateien neu erzeugen (`build_runner`, `flutter gen-l10n`).
+- Web-URLs ohne `#` (`usePathUrlStrategy`): der Webserver braucht eine SPA-Rewrite-Regel (alle Pfade auf `index.html`).

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

+/// Callers can lookup localized strings with an instance of AppLocalizations
+/// returned by `AppLocalizations.of(context)`.
+///
+/// Applications need to include `AppLocalizations.delegate()` in their app's
+/// `localizationDelegates` list, and the locales they support in the app's
+/// `supportedLocales` list. For example:
+///
+/// ```dart

+/// return MaterialApp(
+///   localizationsDelegates: AppLocalizations.localizationsDelegates,
+///   supportedLocales: AppLocalizations.supportedLocales,

+/// ```
+///
+/// ## Update pubspec.yaml
+///
+/// Please make sure to update your pubspec.yaml to include the following
+/// packages:
+///
+/// ```yaml
+/// dependencies:
+///   # Internationalization support.
+///   flutter_localizations:
+///     sdk: flutter
+///   intl: any # Use the pinned version from flutter_localizations

+/// ## iOS Applications
+///
+/// iOS applications define key application metadata, including supported
+/// locales, in an Info.plist file that is built into the application bundle.
+/// To configure the locales supported by your app, you’ll need to edit this
+/// file.
+///
+/// First, open your project’s ios/Runner.xcworkspace Xcode workspace file.
+/// Then, in the Project Navigator, open the Info.plist file under the Runner
+/// project’s Runner folder.
+///
+/// Next, select the Information Property List item, select Add Item from the
+/// Editor menu, then select Localizations from the pop-up menu.
+///
+/// Select and expand the newly-created Localizations item then, for each
+/// locale your application supports, add a new item and select the locale
+/// you wish to add from the pop-up menu in the Value field. This list should
+/// be consistent with the languages listed in the AppLocalizations.supportedLocales
