+## Environment
+
+### Playwright Browsers
+
+- **Issue**: Visual and E2E tests (`npm run test:visual`, `npm run test:e2e`) may fail with `browserType.launch: Executable doesn't exist`.
+- **Workaround**: Run `npx playwright install` to download the required browser binaries if you are running tests outside of the pre-configured dev container or CI environment.
