+
+## Implementation Details
+
+### 1. Application Structure
+
+Create a sample showcase application that demonstrates the UI-Kit in a realistic scenario:
+
+```
+showcase/
+  src/
+    pages/
+      LoginPage.tsx          # Using AuthShell + form components
+      DashboardPage.tsx      # Using MainLayout + stats components
+      CustomersPage.tsx      # Using MainLayout + DataTable
+    components/
+      ProtectedRoute.tsx     # Route protection wrapper
+      Navigation.tsx         # App navigation using UI-Kit components
+    hooks/
+      useAuth.tsx           # Authentication state management
+    services/
+      api.ts                # Mock API for data
+      auth.ts               # Authentication logic
+    types/
+      Customer.ts           # Customer data types
+      Auth.ts               # Authentication types
+```
+
+### 2. Pages Implementation
+
+**Login Page:**
+
+- Use `AuthShell` layout from UI-Kit
+- Login form with `TextInput` and `Button` components
+- Form validation using React Hook Form + Zod
+- Error handling with `Toast` notifications
+- Responsive design following UI-Kit patterns
+
+**Dashboard Page:**
+
+- Use `MainLayout` with navigation and breadcrumbs
+- Summary cards showing customer statistics
+- Quick action buttons using UI-Kit buttons
+- Navigation to customers page
+- Use `StatusBadge` for status indicators
+
+**Customers Page:**
+
+- Use `MainLayout` for consistent navigation
+- `DataTable` component showing customer list
+- Pagination, sorting, and filtering
+- Customer actions (view, edit buttons)
+- Breadcrumb navigation
+
+### 3. Technical Requirements
+
+**Routing:**
+
+- React Router v7 with data loaders
+- Protected routes requiring authentication
+- Proper error boundaries and 404 handling
+- Clean URL structure
+
+**State Management:**
+
+- Authentication state using Zustand (from UI-Kit)
+- Customer data fetching and caching
+- Form state management with React Hook Form
+
+**Data Layer:**
+
+- Mock customer data (50+ records)
+- Simulated API responses with realistic delays
+- Pagination and filtering logic
+- Authentication simulation
+
+### 4. Testing Strategy
+
+**E2E Tests (Playwright):**
+
+- Login flow: invalid credentials → error, valid credentials → dashboard
+- Navigation: login → dashboard → customers → back to dashboard
+- DataTable interactions: pagination, sorting
+- Logout functionality
+- Responsive behavior testing
+
+**Integration:**
+
+- Component integration with real data
+- Form submission and validation flows
+- Navigation state persistence
+- Error handling scenarios
+
+## Definition of Done
+
+**Original DoD:** "E2E Playwright run (login → dashboard) green in CI."
+
+**Expanded DoD:**
+
+- ✅ Showcase application builds and runs without errors
+- ✅ Login page functional with form validation
+- ✅ Dashboard page displays with navigation
+- ✅ Customers page shows DataTable with pagination
+- ✅ E2E Playwright tests pass: login → dashboard → customers flow
+- ✅ All UI-Kit components integrated properly
+- ✅ Responsive design works on different screen sizes
+- ✅ Authentication flow works end-to-end
+- ✅ CI pipeline runs tests successfully
+
+## Technical Dependencies
+
+### Required UI-Kit Components:
+
+- `AuthShell` (login page layout)
+- `AppShell` (dashboard and customers layout)
+- `DataTable` (customers table)
+- `TextInput`, `Button` (forms)
+- `Toast` (notifications)
+- `StatusBadge` (status indicators)
+
+### External Dependencies:
+
+- React Router v7 (routing)
+- React Hook Form + Zod (forms)
+- Playwright (E2E testing)
+- Mock data generation utilities
+
+### Infrastructure:
+
+- Vite setup for showcase app
+- Build integration with UI-Kit
+- CI/CD pipeline updates
+- Development server configuration
+
+## Success Metrics
+
+1. **Functionality:** All user flows work end-to-end
+2. **Performance:** Pages load within 2 seconds
+3. **Accessibility:** axe-core tests pass on all pages
+4. **Testing:** 100% E2E test coverage for critical paths
+5. **Integration:** UI-Kit components work seamlessly
+6. **Maintainability:** Clean, documented code structure
+
+## Next Steps After Completion
+
+This showcase will serve as:
+
+- Reference implementation for UI-Kit usage
+- Testing ground for new components
+- Demo for stakeholders and users
+- Foundation for future showcase extensions (task 3.5: i18n, task 3.6: SQLite integration)
