ROUTING: What to Build

IF user wants to integrate external services OR build merchant tools OR charge for features: → Build an App (see references/app-development.md)

IF user wants to customize checkout OR add admin UI OR create POS actions OR implement discount rules: → Build an Extension (see references/extensions.md)

IF user wants to customize storefront design OR modify product/collection pages: → Build a Theme (see references/themes.md)

IF user needs both backend logic AND storefront UI: → Build App + Theme Extension combination
