+Jest setup (`server/src/tests/setupEnv.ts`) forces `STORAGE=memory`, deletes `MOCK_DATA`, and sets a fixed `JWT_SECRET`. Playwright auto-starts the prebuilt server and authenticates via the `remote-user: e2e-user` trusted-header path; locally uses `STORAGE=json` + `MOCK_DATA=true`, CI uses `STORAGE=redis`.

+### CI pipeline
+Gitea Actions — `.gitea/workflows/ci.yaml` (no `.github/` equivalent):
+
+1. `generate-types` — runs `yarn openapi-ts`, uploads artifact
+2. `server-test` — Jest
+3. `server-build` + `client-build` — parallel tsc/vite builds
+4. `e2e` — Playwright in `mcr.microsoft.com/playwright:v1.59.1-jammy` with a Redis service container; only Firefox installed in CI
+5. `docker-build` — master branch only, uses `Dockerfile-Woodpecker`
+6. `notify` — Discord + ntfy webhooks
