Can I vibe code Printful?

Build a Print-on-Demand Order Management and Mockup Service using Next.js 14, Node.js, and Postgres.

1. DATA MODEL:
- Store: id, name, api_key, webhook_secret
- ProductTemplate: id, title, blank_garment_type, print_areas (JSON bounding boxes), printable_colors (array)
- PrintDesign: id, store_id, product_template_id, overlay_image_url, canvas_json, print_file_url
- Order: id, store_id, external_order_id, shipping_address (JSON), status (pending, processing, fulfilled, canceled), tracking_number
- OrderItem: id, order_id, print_design_id, quantity, size, garment_color

2. CORE FUNCTIONALITY:
- Fabric.js canvas editor API endpoint to load blank garment templates, allow PNG upload, render dynamic preview mockups, and export high-resolution (300 DPI) composite print files.
- Webhook listener endpoint POST /api/webhooks/order-created to parse incoming orders from Shopify/WooCommerce, validate signatures, match line-item variants to PrintDesign IDs, and generate print jobs.
- Admin dashboard displaying incoming orders, automatically flagged low-resolution print assets (<300 DPI), and fulfillment status overrides.
- Vendor Routing module: POST /api/orders/:id/fulfill which formats orders into standardized payload schemas for print networks or direct email dispatch to factory partners.

3. FAILURE MODES TO HANDLE:
- Image scale validation: Throw validation error if uploaded print file resolution falls below 300 DPI at physical print bounding dimensions.
- Out-of-bounds check: Prevent submission if the design canvas object extends beyond defined printable area boundaries.
- Idempotency: Ignore duplicate webhook deliveries using external_order_id keys.

4. OUT OF SCOPE:
- Physical factory equipment integration (Direct-to-Garment RIP software).
- Live carrier shipping label buying (mock tracking numbers instead).
