"""
analysisAI.py — pobiera dane z MySQL, liczy wyłącznie WSKAZANE preagregaty,
renderuje HTML i (opcjonalnie) dodaje analizę AI — tylko jeśli ją zaznaczysz.

Parametry CLI (z formularza PHP):
  --date-from YYYY-MM-DD
  --date-to   YYYY-MM-DD     (zamieniane wewnętrznie na +1 dzień, bo SQL ma warunek '< date_to')
  --metric    NAZWA          (można podać wiele razy: --metric a --metric b ...)
  --metrics   CSV            (opcjonalnie alternatywnie: --metrics a,b,c)
  --ai        true|false     (czy uruchomić analizę AI — tylko gdy są preagregaty z danymi)

Preagregaty:
  - kpis (aliasy: basic, basic_totals) — podstawowe KPI: sprzedaż, ilość, dokumenty, ASP
  - daily_sales, product_summary, customer_summary, product_daily,
    top10_products_by_sales, top10_customers_by_sales  (z preaggregates.py)
