/* ═══════════════════════════════════════════════════════════════
   Zim Rail Menu — reużywalny sidebar nawigacyjny (Deep Navy / Steel Blue)
   Źródło stylu: Cowork/cowork.html ("Zim Platform" theme).
   Zawiera: zmienne motywu, lewy pasek (rail), zachowanie mobilne
   (hamburger + przeciągnięcie od krawędzi), minimalny wrapper treści
   (.content, .view/.view.active, view-title/view-sub).

   Reszta stylów widoków (karty, tabele, pigułki itd.) NIE jest częścią
   tego pakietu — dokładane osobno przez każdy projekt, który z niego
   korzysta.
