## 🔧 Technical Implementation

### CSS Variables
```css
:root {
  --primary-green: #10b981;
  --primary-dark: #047857;
  --primary-darker: #064e3b;
  --accent-green: #059669;
  --bg-dark: #065f46;
  --sidebar-bg: #0f766e;
  --sidebar-hover: #14b8a6;
  --card-bg: rgba(255, 255, 255, 0.98);
  --border-color: rgba(16, 185, 129, 0.2);
}
```

### Component Architecture
```
Dashboard
├── Sidebar (navigation)
├── Header (branding + user)
├── TabNavigation (Search/Results/Details)
└── Content Area
    ├── TransactionSearch (form)
    ├── Results Display (table)
    └── Details View (coming)
```

### State Management
- `activeSection` - Current sidebar section
- `activeTab` - Current tab (search/results/details)
- `searchResults` - Search results data
- `user` - User information

---

## 📚 Code Examples

### Using the Components

```tsx
// In dashboard/page.tsx
import Sidebar from '@/components/layout/Sidebar';
import Header from '@/components/layout/Header';
import TabNavigation from '@/components/layout/TabNavigation';
import TransactionSearch from '@/components/search/TransactionSearch';

export default function DashboardPage() {
  const [activeSection, setActiveSection] = useState('transaction');
  const [activeTab, setActiveTab] = useState('search');
  const [searchResults, setSearchResults] = useState(null);

  return (
    <div className="flex h-screen">
      <Sidebar 
        activeSection={activeSection} 
        onSectionChange={setActiveSection} 
      />
      <main className="flex-1 flex flex-col">
        <Header />
        <TabNavigation 
          activeTab={activeTab} 
          onTabChange={setActiveTab} 
        />
        <div className="flex-1 overflow-y-auto p-8">
          {/* Content based on activeTab */}
        </div>
      </main>
    </div>
  );
}
```

## 🔥 Performance

The Next.js version will be faster because:
- ✅ Code splitting (loads only what's needed)
- ✅ Tree shaking (removes unused code)
- ✅ Optimized images
- ✅ Built-in caching
- ✅ React's virtual DOM (efficient updates)

---

## 📝 Notes

### Component Props Pattern
All components use TypeScript interfaces for props:
```typescript
interface SidebarProps {
  activeSection: string;
  onSectionChange: (section: string) => void;
}
```

### API Integration
Using axios with interceptors for automatic token handling:
```typescript
const response = await apiClient.get('/transactions/search?params');
```

### State Management
Currently using React useState. For complex state, we can add:
- Zustand (global state)
- React Query (server state)
- Context API (auth state)
