Can I vibe code Sellix?

Build a full-stack digital product e-commerce application using Next.js (App Router), Tailwind CSS, Supabase (Database & Auth), and Stripe. 1. Data Model: Create PostgreSQL tables for `products` (id, title, description, price_cents, type ['file'|'license_key'|'subscription']), `product_files` (id, product_id, file_path), `license_keys` (id, product_id, key_code, status ['available'|'claimed'], order_id), `orders` (id, user_email, status, total_cents, stripe_session_id), and `order_items` (id, order_id, product_id, delivered_payload). 2. Storefront UI: Implement a responsive catalog page showing available products, a detail view for individual products, and a cart drawer. 3. Checkout: Use Stripe Checkout Sessions API to process fiat payments. Create an endpoint `/api/checkout` that creates a Stripe session with line items and metadata containing order details. 4. Webhook Fulfillment Engine: Implement `/api/webhooks/stripe` with signature verification. On `checkout.session.completed`: create an order record, atomic transaction to mark assigned license key as 'claimed' if product type is 'license_key', or generate a short-lived signed S3 download URL (valid 1 hour) if type is 'file'. Send an email via Resend with the claimed key or download link. 5. Edge Cases & Safety: Use PostgreSQL transactions with row-level locks (`FOR UPDATE`) when pulling license keys from the pool to avoid duplicate key assignments under high concurrency. Handle Stripe webhook retries gracefully with idempotency keys. Out of scope: Crypto wallet payments and multi-currency blockchain indexers.
