-- `npm run test:e2e` — runs all Playwright tests (headless Chromium).
-- Requires `docker compose up` (backend + frontend running).
-- Config: `frontend/playwright.config.ts`.
-- Tests: `frontend/e2e/*.spec.ts`.

+### E2E (Playwright) — **Docker only**
+
+**Agents and humans: never run Playwright on the host.**
+
+| Do **not** run | Why |
+|----------------|-----|
+| `npx playwright test` | Wrong environment; needs Docker stack |
+| `npm run test:e2e` | Same — host Playwright, not supported for agents |
+| `npx playwright install` | Do not install browsers on the host; the Playwright image already includes them |
+
+**Always use Docker** (`docker-compose.e2e.yml`): isolated postgres (tmpfs), backend, frontend, Mailpit, and the official Playwright container on the `e2e` network (`PLAYWRIGHT_BASE_URL=http://frontend`).
+
+**Full E2E suite** (same as Forgejo CI / `./gradlew check`):
+
+```bash
+# from repo root — set env (or use .env; see .env.example)
+cd frontend && npm run test:e2e:ci
+# equivalent:
+./gradlew frontendE2E
+```
+
+**Single spec or project** (stack must be reachable on the `e2e` network):
+
+```bash
+# from repo root, after exporting the same vars as frontendE2E / .env
+docker compose -f docker-compose.e2e.yml up -d --build postgres mailpit backend frontend
+docker compose -f docker-compose.e2e.yml run --rm --build playwright \
+  sh -c 'npx playwright test admin-fulfillment.spec.ts --project=chromium-serial --reporter=list'
+docker compose -f docker-compose.e2e.yml down
+```

+- Config: `frontend/playwright.config.ts`
+- Tests: `frontend/e2e/*.spec.ts`
+- Serial specs (shared Mailpit / seeded DB): `admin-fulfillment`, `deferred-payment-admin`, `admin-dashboard`, `account-settings`, `password-reset` — project `chromium-serial` runs **after** parallel `chromium`, `workers: 1`
 
 ### CI (future)
 - `./gradlew check` and `npm run test && npm run lint` must pass before merge.
