Theme app extension

Definition

The modern (Online Store 2.0) mechanism Shopify apps use to inject blocks into a theme's sections, replacing older raw script-tag injection. Better for merchant control and removal, but still loads app JavaScript on render — consolidation still matters even on OS 2.0 themes.
