Store ID as a border
Search events, product clicks, orders and configuration should always be processed within the same store context.
Store Separation
Each shop must keep its own data and configuration.
Multi-store management may enable central operation without mixing search behavior, settings or conversions between stores.
Own institutions
Language, theme, filters, AI assistant, quick view and merchandising may vary by store.
Own analytics
Reports and recent conversions should not display data from other stores under the same account.
Own data storage
A clear store separation supports management, migration and technical transferability.
Account level
Central account functionality should be explicitly distinguished from store-specific functionality.
Testing
Use multiple stores in acceptance tests to make cross-store regressions visible before changes go live.
