"""Manual functional e2e for the Google Maps scraper (app/proprietary/scrapers/google_maps).

Run from the backend directory:
    cd surfsense_backend
    uv run python scripts/e2e_google_maps_scraper.py
    # or: .\\.venv\\Scripts\\python.exe scripts/e2e_google_maps_scraper.py

NOT a pytest test (needs live network + optional proxy creds). It:
  Step 1 — scrapes a known place URL and prints the core fields.
  Step 2 — scrapes the same place by bare placeId (HTML -> fid -> RPC path).
  Step 3 — dumps the raw place darray (jd[6] of /maps/preview/place) to
      tests/unit/scrapers/google_maps/fixtures/ for the offline parser test.
  Step 4 — scrapes reviews via the Reviews endpoint (BOQ feed), checks fields.
  Step 5 — paginates past one page (maxReviews=15) and checks the count.
  Step 6 — place scrape with maxReviews>0 attaches inline reviews[].
  Step 7 — dumps a raw BOQ reviews page fixture for the offline parser test.
  Step 8 — search discovery (searchStringsArray + locationQuery), checks items.
  Step 9 — dumps a raw map-search response fixture for the offline parser test.
