- Test for ProductQuery engine and ProductFilters engine - Test for engine for Item Group too - Renamed ‘product_configurator’ to ‘variant_selector’ - Cleaned up filters.py - Modal freeze backdrop lighter only in cart, since there’s nothing over it - Fixed unusual spacing in variant selector dialog - Made `get_child_groups_for_website` more readable - Replaced ‘Configure’ with ‘Select’ for variant selection
