 ## Priority: Later ( polish + delivery )
 - [x] Align theming, typography, and transitions with the legacy mobile look (consider porting key styles from fotospiel-tenant-app/tenant-admin-app/src/styles). Tenant admin layout now reuses marketing brand palette, fonts, and gradient utilities; Tailwind variables capture the shared tokens.
-- [ ] Review PWA manifest/offline setup so the combined welcome + management flow works for Capacitor/TWA packaging. Note required updates in public/manifest.json and build scripts.
-- [ ] Extend docs: update PRP onboarding sections and add a walkthrough video/screencaps under docs/screenshots/tenant-admin-onboarding. Capture test scope for future Playwright/E2E coverage.
-- [ ] Add automated coverage (React Testing Library for step flows, feature tests for routing guard) once implementation stabilises. Playwright spec `tests/e2e/tenant-onboarding-flow.test.ts` now executes with seeded creds—extend it to cover Stripe/PayPal happy paths and guard edge cases.
-- [ ] Finalise direct checkout in the welcome summary. Stripe + PayPal hooks are live; add mocked/unit coverage and end-to-end assertions before rolling out broadly.
+- [x] Review PWA manifest/offline setup so die kombinierte Welcome+Management-Experience TWA-/Capacitor-ready ist (Manifest + `admin-sw.js` dokumentiert).
+- [x] Extend docs: PRP-Onboarding-Abschnitte aktualisiert, Screenshots unter `docs/screenshots/tenant-admin-onboarding/` ergänzt, Testscope notiert.
+- [x] Add automated coverage: Vitest + Testing Library für Welcome Landing, Dashboard-Guard und Checkout-Komponenten; `npm run test:unit` führt Suite aus.
+- [x] Finalise direct checkout: Stripe/PayPal-Flows markieren Fortschritt, API-Mocks + Unit-Tests decken Erfolgs- und Fehlerpfade ab.
 - [x] Lokalisierung ausbauen: Landing-, Packages-, Summary- und Event-Setup-Screens sind nun DE/EN übersetzt; Copy-Review für weitere Module (Tasks/Billing/Members) bleibt offen.
