- /auth/login no longer asks for a myshopify domain (App Store 2.3.1). With
?shop= it still hands off to OAuth; otherwise it points to Shopify.
- Billing API charges are test charges outside production and on partner
development stores (shop.plan.partnerDevelopment), so reviewers can pick a
paid plan. Real shops are charged as before.
- SCREENCAST.md matches the recording.
