- purchase: id→item_id (string), name→item_name, price fallback na price_brutto gdy brak promo, user_data poza ecommerce
- begin_checkout: id→item_id, name→item_name, dodano google_business_vertical
- Usunięto fałszywą konwersję GADS (gtag conversion) ze strony checkout
- view_item: dodano currency PLN, price jako number zamiast string
- Dodano event view_cart na stronie koszyka
- add_to_cart: quantity parseInt zamiast string
