Get a private page showing the setup, where the build is underbuilt, and the four things to build to fix it — with the actual code, ready to paste.
Reads what's visible on the storefront — apps detected, theme, currency, product range, the collections they expose, and any subscription / wholesale signals. No login, no admin access.
Then: a sketch of where the build looks light, with the actual code to add. A real reference for your dev, not a sales deck.
