Can I vibe code Ordercup?

Build a multi-channel order aggregation and shipping label web application using Next.js (App Router), Tailwind CSS, PostgreSQL, and Prisma ORM, integrating with the EasyPost API for rate shopping and label generation.

1. DATA MODEL:
- Store: id, platform ('shopify' | 'woocommerce'), api_credentials (encrypted JSON), created_at.
- Order: id, store_id, external_order_id, recipient_name, address_line1, address_line2, city, state, postal_code, country, items (JSON array), fulfillment_status ('unfulfilled' | 'purchased' | 'shipped'), created_at.
- PackagePreset: id, name, length_in, width_in, height_in, weight_oz.
- Label: id, order_id, carrier, service, tracking_code, label_url, cost, created_at.

2. CORE FUNCTIONALITY:
- Order Aggregation: Webhook handlers for incoming orders from Shopify and WooCommerce that parse and insert standard order objects into PostgreSQL.
- Rate Engine: UI to view unfulfilled orders, assign package dimensions or pick a PackagePreset, and call the EasyPost API to display real-time rates sorted by lowest cost.
- Purchasing & Sync: Action to purchase the selected rate via EasyPost API, save the label PDF/ZPL URL, and push a webhook update back to Shopify/WooCommerce with the carrier tracking number to mark the store order as fulfilled.
- Batch Processing: Bulk selection tool in the order table to assign a single package preset, automatically select the cheapest ground rate for each order, and assemble a batch label PDF.

3. PRINTING & FAILURE HANDLING:
- Embed WebSockets hooks designed to pass ZPL string payloads to a local QZ Tray printer daemon for silent thermal printing.
- Catch carrier address validation failures gracefully and surface editable address fields in the UI before requesting rates.
- Handle API failures with structured toast notifications and exponential backoff retry logic.

4. OUT OF SCOPE:
- Direct carrier SOAP/XML connections without API wrappers.
- Complex customs generation for non-standard international cargo.
- Automated carrier billing reconciliation dashboards.
