This is a separate backend fork copied from the existing ArtifyPets app. Keep the current production app untouched and adapt this project for Shopify proof approval, cart mapping, order webhooks, and final-art delivery.

Copied service areas

• Proof image generation
• Supabase storage and order records
• Shopify payment-gated final-art downloads
• Meta Conversions API
• Admin production/shipping routes
• Stripe checkout and webhook routes for reference
