/* ------------------------------------------------------------------
   vgui.css
   Source engine VGUI-style dialog styling.
   Emulates the look of Half-Life 2 / Source 2004 VGUI panels:
   charcoal panels, raised tabs with an inner content frame, sunken
   image wells, flat Tahoma typography and small chiseled buttons.

   NOTE on specificity:
   Blazor's CSS isolation rewrites `*` resets in `.razor.css` files to
   `*[b-xxxxx]`, which has the SAME specificity (0,1,0) as a single
   class. When this stylesheet is loaded before the scoped bundle the
   reset wins on source order and zeroes our padding/margins out.
   Every rule below is therefore scoped under `.vgui-overlay` so each
   selector lands at 0,2,0 and reliably wins the cascade.
