Build My First Online Store

Help me build a complete ecommerce MVP as a beginner using Next.js, TypeScript and Tailwind CSS.

Include a product catalogue, product detail pages, search, categories, filters, cart, checkout, customer account, order history and an admin product management area. Prepare the payment architecture for Paystack or Stripe without choosing credentials for me. Never store card information; use the payment provider's hosted or tokenized flow. Explain server-side price validation, quantity limits, webhooks, order states, authentication, authorization, validation, loading/error/empty states, SEO and deployment. Use Next.js with TypeScript and Tailwind CSS. Build a polished, accessible, responsive application with clear beginner explanations, reusable components, semantic HTML, loading/error/empty states, form validation, SEO metadata, dark/light mode and deployment instructions. Explain important decisions as you go.
