- Tenant-Admin-PWA: Neues /event-admin/welcome Onboarding mit WelcomeHero, Packages-, Order-Summary- und Event-Setup-Pages, Zustandsspeicher, Routing-Guard und Dashboard-CTA für Erstnutzer; Filament-/admin-Login via Custom-View behoben.

- Brand/Theming: Marketing-Farb- und Typographievariablen in `resources/css/app.css` eingeführt, AdminLayout, Dashboardkarten und Onboarding-Komponenten entsprechend angepasst; Dokumentation (`docs/todo/tenant-admin-onboarding-fusion.md`, `docs/changes/...`) aktualisiert.
- Checkout & Payments: Checkout-, PayPal-Controller und Tests für integrierte Stripe/PayPal-Flows sowie Paket-Billing-Abläufe überarbeitet; neue PayPal SDK-Factory und Admin-API-Helper (`resources/js/admin/api.ts`) schaffen Grundlage für Billing/Members/Tasks-Seiten.
- DX & Tests: Neue Playwright/E2E-Struktur (docs/testing/e2e.md, `tests/e2e/tenant-onboarding-flow.test.ts`, Utilities), E2E-Tenant-Seeder und zusätzliche Übersetzungen/Factories zur Unterstützung der neuen Flows.
- Marketing-Kommunikation: Automatische Kontakt-Bestätigungsmail (`ContactConfirmation` + Blade-Template) implementiert; Guest-PWA unter `/event` erreichbar.
- Nebensitzung: Blogsystem gefixt und umfassenden BlogPostSeeder für Beispielinhalte angelegt.
