/* Geofile — explorer.css
   The window chrome (title bar, controls, borders, body background) comes
   from XP.css. This file only styles what XP.css doesn't:
     • toolbar (back/forward, view chips, address bar, search)
     • sidebar with location/topic shortcuts
     • content area with folder/file icons + grid/list layouts
   .explorer-pane positioning + window-body padding override live in desktop.css. */
