/* ------------------------------------------------------------------------------------------
   Navigation shell for the landlord app: sidebar, top bar and the page frame around them.
   This is the only stylesheet that styles .sidebar / .topbar / .main / .content. It is loaded
   last on every landlord page, after theme.css, app.css and ui.css.

   States (set by shell.js):
     .sidebar.is-wide   labels visible (hover peek, pinned on desktop, or the phone drawer)
     .sidebar.is-peek   expanded as an overlay above the content (no layout shift)
     .sidebar.is-open   phone drawer open
     :root[data-nav-pinned="1"]   user pinned the sidebar (desktop >= 1100px pushes content)
