 Test files live in `e2e/` and share helpers from `e2e/helpers.ts`:
 
+### Local startup troubleshooting
+
+For targeted local work, confirm a new or changed test is discoverable before starting the dev server:
+
+```bash
+./node_modules/.bin/playwright test e2e/pinning.spec.ts --grep "test name" --list
+```
+
+Then run a non-watch Stencil build to catch compile errors without invoking the Playwright web-server lifecycle:
+
+```bash
+./node_modules/.bin/stencil build --dev --serve --no-open
+```
+
+If Playwright fails before any tests run with a Stencil dev-server startup error such as `ERR_SOCKET_BAD_PORT` and port `65536`, treat it as an environment/startup issue rather than an e2e assertion failure. Check `node -v` and whether another local server is already using `localhost:3333`, then retry only after changing that environment state.
