/* ============================================================================
   rz-layout.css  —  Radzen-style ICON SIDEBAR shell (responsive)
   ----------------------------------------------------------------------------
   Pairs with the replacement _Layout.cshtml. Load AFTER site.css:
       <link rel="stylesheet" href="~/css/rz-layout.css" asp-append-version="true" />

   Behaviour
     Desktop  : slim 66px icon rail; hover expands to a 256px panel (overlay,
                content does NOT reflow). A pin button keeps it open.
     Mobile   : rail hidden; hamburger slides in a full 256px drawer + backdrop.
   Only affects the authenticated shell (login page has no .rzl-* elements).
