/* =====================================================================
   blog.css — lista wpisów (/blog, /blog/kategoria/{slug})
   ---------------------------------------------------------------------
   Arkusz wydzielony z gotowej podstrony `blog/index.html`. Zawiera to, co
   specyficzne dla listy: nagłówek strony, wyszukiwarkę, chipy kategorii,
   przełącznik widoku, karty wpisów (wyróżniony, siatka, lista), panel boczny,
   paginację i stan pusty.

   Tokeny motywu (kolory, fonty) i style wspólne są w `site.css`, który
   ładujemy PRZED tym plikiem. Reguły powtarzające się między arkuszami
   zostały z tego pliku usunięte, żeby nie tworzyć dwóch prawd.
