Implementing an Interactive Block Blast Solver Widget on Shopify Without Impacting Store Performance

What’s the best approach to implement a custom Shopify app or embedded widget that lets users interact with a Block Blast Solver like http://blockblastsolverlive.com/, uploading screenshots and getting move suggestions—without affecting store performance?

Use Shopify’s API for integration and offload image processing to a cloud service like AWS to avoid slowing down the store. Embed the solver via an iframe or App Bridge for a smooth user experience.
