"""
Verifica daca pagina de login BT e inca la fel (campuri user/parola/submit).

Fara credentiale, fara .env: doar deschide pagina de login ca scraper-ul,
o observa si iese cu cod 0 daca formularul e intact, altfel 1 + motivul.
Nu completeaza campuri si nu submite nimic.

Chromium e lansat identic cu btgo_scraper.py (noul mod headless
--headless=new + UA de Chrome normal), altfel WAF-ul Akamai al BT raspunde
cu Access Denied. Nu folosim networkidle (nu se atinge niciodata pe site-ul
BT) -> domcontentloaded + asteptari pe selector.

Nota: lansarea browserului e duplicata din btgo_scraper.run() pentru ca
acolo e inline si btgo_scraper importa config (care citeste .env). Daca
lansarea va fi extrasa intr-un helper fara config, scriptul il poate importa.
