/*
 * Instrukcje obsługi (/user-manuals/).
 *
 * Lista plików PDF pogrupowana w akordeony per język (natywne <details>/<summary>,
 * bez JS) i w sekcje per wersja urządzenia. Paleta i promienie jak w przewodniku
 * DWO, żeby obie strony „dokumentowe" wyglądały jak jedna rodzina.
 *
 * Tylko tryb ciemny — tryb jasny wykluczony z projektu, brak reguł [data-theme="light"].
 * Wszystko scope'owane pod .manuals, żeby nie wyciekać do reszty motywu.
