Can I vibe code Orderify?

Build a self-service Shopify Order Editing and Cancellation app using Node.js and Remix that runs behind a Shopify App Proxy.

1. AUTHENTICATION & SECURITY:
- Implement HMAC verification middleware for all requests originating from Shopify App Proxies.
- Restrict edit operations to requests containing valid `order_id` and logged-in customer session tokens.

2. CORE FUNCTIONALITY:
- Render an embedded widget on the Shopify Order Status page.
- Fetch current order status from Shopify Admin GraphQL API (`orders(id)`).
- Implement 'Cancel Order': If fulfillmentStatus is UNFULFILLED and order age is less than 60 minutes, execute `orderCancel` mutation. Automatically trigger full refund via default payment gateway.
- Implement 'Update Shipping Address': If fulfillmentStatus is UNFULFILLED, allow customer to submit updated address fields and call `orderUpdate` mutation with new address payload.
- Implement 'Item Swap/Edit': Execute `orderEditBegin`, call `orderEditRemoveLineItem` or `orderEditAddVariant`, and finalize with `orderEditCommit` to handle dynamic price adjustments.

3. ERROR HANDLING & FAILURE MODES:
- Block edits immediately if order status updates to FULFILLED or IN_TRANSIT during user session.
- Catch gateway errors during price recalculations and notify customer to contact support if automated refund/charge fails.
- Return clear validation error messages when address format fails carrier validation checks.

4. OUT OF SCOPE:
- Custom payment gateway processing outside Shopify Payments.
- Warehouse management system (WMS) inventory direct syncs.
