Create a modern SaaS Inventory Management System with the following capabilities:

1. User Authentication & Management

   • Integrate Supabase Auth to handle secure sign-up, login, and OAuth (Google, GitHub, etc.).
   • Implement Role-Based Access Control (RBAC) using Supabase Row Level Security.
   • Define user roles: Admin (full access), Manager (inventory management), and Staff (view-only).

2. Inventory Management

   • Build features to add, update, delete, and view inventory items.
   • Each inventory item should include fields like name, category, quantity, price, and images.
   • Include an option for generating barcodes/QR codes for inventory items.

3. Data Export Functionality

   • Allow users to export inventory data in CSV, PDF, and Word formats.
   • Use client-side libraries (e.g., PapaParse) for CSV generation.
   • Utilize serverless functions or API endpoints (with libraries like pdfkit for PDF and docx for Word) for document generation.
   • Store or manage these files using Supabase Storage.

4. Dashboard & Reporting

   • Develop a responsive dashboard using v0.dev components.
   • Display interactive charts (using built-in chart components or third-party libraries) to show inventory trends.
   • Include filtering, sorting, and search functionality on inventory data.

5. Notifications & Real-Time Updates

   • Implement in-app notifications for events like low stock.
   • Leverage Supabase real-time subscriptions for immediate UI updates.
