+# E2E
+
+Copy `.env.e2e.example` to `.env.e2e`. The DB name must contain `e2e`; scripts reject any other name.
+
+Run `yarn e2e:db:up`, `yarn playwright install chromium`, then `yarn e2e`. Use `yarn e2e:db:down` to discard the isolated DB.
+
+Authentication is performed once by Playwright global setup through the UI, then saved as browser storage state. This is required because `react-secure-storage` encrypts its local storage values.
