+### End-to-end tests (Playwright)
+
+The e2e tests live in `e2e/` and use Playwright with a real browser. Each test
+starts its own server against a fresh, throwaway database on a unique port, so
+tests are fully isolated from each other and from your real `sustenance.db`.
+
+The tests launch `target/debug/sustenance`, so build the server first:
+
+```sh
+# one-time setup
+cargo build
+cd e2e
+npm install
+npx playwright install chromium
+
+# run the tests (each test launches its own server against a fresh DB)
+cd e2e
+npx playwright test
+```
