/* ─────────────────────────────────────────────────────────────────────────
   Legacy sheet, now reduced to the login screen.

   The old Material chrome (dark sidebar, app bar, user menu) lived here and
   was only ever consumed by Pages/Shared/_Layout.cshtml. The Blazor app uses
   leaf-shell.css and _Layout now renders a slim design-system topbar, so all
   of it has been removed along with its Material-blue token block. Base
   typography and the body background come from leaf-shell.css.
