Shopify RAG Chatbot UI Fixes

I already have a fully working RAG-based chatbot backend for my Shopify app; what’s missing is the customer-facing layer. I need a clean, responsive conversational interface that feels native inside a Shopify store, hooks seamlessly to the existing endpoints, and ultimately goes live on the production store.

Here’s what I’m looking for you to handle:
• Design and build the chatbot UI (desktop and mobile) using Shopify-friendly tech such as Polaris, React and Liquid.
• Connect the interface to my RAG backend, handling auth, context and error states.
• Track down and resolve the current batch of frontend bugs (I’ll share the list and repo access).
• Package, test and deploy the updated app to the Shopify store environment, verifying everything in both the admin and storefront views.

Acceptance criteria
• UI matches approved Figma mock-ups across breakpoints and browsers.
• All critical bugs on the supplied list are closed with clean, commented code.
• Chatbot responds through the new UI with the same accuracy and latency as the existing test harness.
• Final build passes Shopify review and is published without regressions.

If you have solid Shopify app experience, a good eye for UX and confidence shipping React/Polaris code, I’d love to work with you.
