+- Protected by servicepipe.ru PoW — headless browsers get stuck in redirect loop at `/xpvnsulc/`
+- **Requires VNC login first**: open VNC, navigate to `https://www.perekrestok.ru/`, wait 10s for servicepipe challenge to resolve, save session
+- After login: search uses Playwright browser with saved cookies, also tries `/api/v1/catalog/product/search` directly
+- Session expiry check: if browser lands on `/xpvnsulc/` URL, session is stale → re-login
