 - Fixture page served via Playwright `webServer` + custom static server:
   - `e2e/serve-fixtures.mjs`
+  - `playwright.config.ts` currently uses `webServer.command: node e2e/serve-fixtures.mjs 51234`
   - `playwright.config.ts` points `webServer.url` at `http://localhost:51234/inspector-playground.html`
   - `use.baseURL` is `http://localhost:51234`
   - Tests navigate with relative paths like `/inspector-playground.html`
+  - `e2e:preview` is available as `vite preview --host localhost --port 51234 --strictPort` for local/CI experiments, but is not the default command until startup is stable in CI
