   KNOWLEDGE.CSS — Baza Wiedzy (archive-artykul.php, single-artykul.php,
   taxonomy-zwierze.php). Ładowany WYŁĄCZNIE na tych trzech typach stron
   (patrz functions.php → szczurkowo_enqueue_assets), po main.css.

   Zero równoległego systemu: kolory, spacing, typografia, .btn/.card/.chip/
   .book/.photo-slot/.kb-featured/.container pochodzą z main.css. Ten plik
   dodaje WYŁĄCZNIE geometrię sekcji specyficzną dla Bazy Wiedzy (namespace
   .kb-*), tak jak home-master.css robi to dla strony głównej (.sz-*).
