/* ===========================================================
   12. Layout: opis produktu jako osobna sekcja na pełną szerokość
   ===========================================================
   Motywy oparte na flex/grid (WoodMart, Astra, Storefront, Flatsome)
   często wpychają długi opis produktu do lewej kolumny pod galerią.
   Te reguły wymuszają, żeby pełny opis był osobną sekcją na całą
   szerokość pod galerią + summary, przed sekcją "Podobne produkty".

   Targetowane elementy:
   - .qrwc-product-description (plugin Quote Request for WooCommerce)
   - .woocommerce-product-description (standardowy WC w niektórych motywach)
   - .product .description (alternatywne klasy)
