+"""Eksport raportu interpretacji do Excela — „tabela robocza" (DAN-23 / PRE-10).

+Raport z logiki jest zagnieżdżony: obiekt → fasety → próbki (dopasowania z bazy).
+Astrolog chce z tym PRACOWAĆ w Excelu: filtrować, sortować, zaznaczać, usuwać —
+więc spłaszczamy go do JEDNEJ płaskiej tabeli (wiersz = jedno dopasowanie) z
+auto-filtrem i zamrożonym nagłówkiem. Bez wykresów i ozdób — to materiał roboczy.
+
+Świadomie budujemy plik TU, w prezentacji (jak PDF idzie przez usługę render):
+warstwa danych/logiki liczy, prezentacja formatuje wyjście.
