A full-stack marketplace with glassmorphism UI, role-based access, real-time notifications, Razorpay payments, and a seller analytics dashboard.

• JWT-based auth with bcrypt password hashing — 30-day token expiry
• Three role types: Buyer, Seller, Admin (only one admin allowed per platform)
• Profile management with avatar upload, editable email + name, address book (Home/Office/Other)

• Product discovery with category filter, price range filter, and 4-way sort (price, newest, top-rated)
• Live search bar with debounced autocomplete, image previews, and highlighted matches
• Full search results page with server-side pagination, sorting, and price filters
• Product comparison — select up to 3 products and compare price, stock, category, description side-by-side
• Recently viewed products persisted via localStorage on each product detail page
• Wishlist toggle per product, viewable from profile
• Multi-image product gallery with thumbnail selector

• Add to cart with stock validation, quantity increase/decrease, item removal
• Coupon system — admin creates discount codes with expiry, usage limits, and enable/disable toggle
• Checkout flow: Cart → Select Address → Order Confirmation → Payment
• Razorpay integration for online payment with HMAC signature verification
• COD (Cash on Delivery) as alternative payment method

• Buyer order history with a 4-step progress stepper (Pending → Processing → Shipped → Delivered)
• Timestamped status history per step
• Order cancellation by buyer (creates notification)
• Seller order management with status update dropdown

• Revenue, order count, product count, average rating stats
• CSS bar chart of top-selling products (no chart library — pure CSS animations)
• Recent orders list with status badges
• Top products table with units sold and revenue generated per product

• In-app notification bell with unread badge counter
• Auto-generated notifications on order status changes and cancellations
• Mark individual or all notifications as read; click to navigate to relevant page
• Polling every 60 seconds for fresh data

• Platform-wide stats: users, products, orders, total revenue
• User role management table (promote/demote any user)
• Full coupon CRUD: create, list, enable/disable

• Glassmorphism design system with dark/light theme toggle (persisted to localStorage)
• CSS variable token system (--color-accent, --surface, --border, etc.)
• Outfit display font + Inter body font
• fadeInUp, spin, growUp keyframe animations throughout
• Responsive down to 480px — mobile-first cart and navbar
