/* App shell surfaces that MudBlazor renders itself. These classes are handed
   to MudAppBar/MudText via their Class parameter, so they land on markup that
   MainLayout.razor.css can never reach — its scope attribute is only stamped
   onto that file's own literal elements, and no ancestor of the app bar
   carries it either, which makes ::deep useless here too. This stylesheet is
   linked after MudBlazor.min.css, so equal-specificity rules win on order. */

/* The navigation rail's surface.
   Global, not scoped: MudDrawer renders its own <aside> and no ancestor carries
   MainLayout.razor.css's isolation attribute, the same constraint the app bar
   above has.
   MudBlazor paints the drawer from PaletteDark.DrawerBackground, which was
   #08131b — DARKER than the #0b1117 canvas, so in dark mode the rail sank into
   a black gutter instead of floating. The platform's rail is the card tier at
   85% with a blur behind it, one step ABOVE the canvas, and that is what the
   React shell's aside already does. This matches them. */
