/* ============================================================
   WinMan — Fenstermanager (Plattform Phase 3)
   Vanilla, jQuery-frei. Vorbild: ts_application_v2 (app.ui.js dialog/win/taskbar).
   Desktop: schwebende, verschieb-/stapelbare Fenster + Taskbar.
   Mobil (<=900px): Vollbild-Sheets (unter der Topbar), Taskbar als Minimierleiste.

   z-index: .lk-winhost ist eigener Stacking-Context (z-index:55) -> Fenster liegen
   UEBER dem Dokument-Header im Content (z50), aber UNTER den Shell-Overlays
   Modal(60)/Toast(80)/Idle(90). Taskbar z58 (ueber Fenstern, unter Modal).
