I'll build a production-ready Next.js frontend for ZCore based on your comprehensive requirements. Let me start by understanding the current codebase structure, then create a complete application with all the features specified.

Now I'll build the complete ZCore frontend application with all the required features. This will include the landing page, auth pages, dashboard with all functional areas, and the necessary infrastructure components.

I've built a complete production-ready ZCore frontend application! Here's what I've created:

Core Infrastructure:

• API client with error handling and JWT token management
• Auth service for localStorage token/user management
• Reusable API response card component for consistent feedback
• Auth guard for protected routes
• Professional dashboard navigation

Pages Implemented:

1. Landing Page - Professional hero section with value propositions, "How it Works" steps, features showcase, and CTAs for login/register
2. Register - Complete questionnaire form (email, password, wallet, name + 5 financial questions)
3. Login - Simple auth with JWT storage and redirect to dashboard
4. Dashboard (Scoring) - Request scoring evaluations with optional additional data
5. Search Profile - Look up users by wallet address
6. Lender Profiles - Create risk profiles with amount ranges and rates, plus a table showing created profiles
7. Payments - Report paid/default status to update credit scores

Design & UX:

• Clean fintech/Web3 aesthetic with a blue color scheme conveying trust
• Fully responsive mobile-first layout
• Consistent loading states, success/error alerts
• Pretty-printed JSON responses for API data
• Auth status display and easy logout

The app connects to your backend API at http://localhost:3000 (configurable via env var) and handles all authentication, error states, and data display professionally.

Fixed the globals.css file to include all required sidebar color variables in the @theme inline section. The custom blue color scheme for ZCore is preserved while ensuring compatibility with all shadcn/ui components.
