// Tests E2E (integration_test). Corren sobre dispositivo/emulador real:

// A diferencia de los widget tests de `test/`, estos arrancan la app completa
// (router, Riverpod, tema) en un binding de integración, sirviendo de base para
// flujos end-to-end (login → POS → venta) en sprints siguientes.
