Technical Implementation

Frontend Architecture

The application follows a component-based architecture with clear separation of concerns:

src/
├── app/                 # Next.js App Router
├── components/          # Reusable UI components
├── lib/                # Utility functions and data loading
├── types/              # TypeScript type definitions
