/* Sparse/few-column grids: MudBlazor's ColumnResizeMode="ResizeMode.Container"
   inlines `width: max-content` on the .mud-table-container element (the grid's
   scroll wrapper — see MudDataGrid TableStyle). That makes the container
   shrink-wrap to the columns' intrinsic width, so a grid with few columns ends
   up narrower than its host and leaves whitespace on the right. Because the
   value is applied INLINE, only an `!important` author rule can override it.
   Forcing the container to 100% (while keeping MudBlazor's inline overflow-x:auto)
   makes the grid edge-to-edge; genuinely wide grids whose content exceeds 100%
   simply scroll inside the container as before — so this is a floor, never a
   ceiling, and does not regress wide grids. */

 * colour-specific rule and falls back to the base .mud-button-filled, which is
 * dark text (text-primary) on a near-transparent grey (action-default-hover).
 * On a coloured DashboardHeader gradient that reads as illegible dark-on-blue.
 *
 * Provide the missing treatment: a solid surface-coloured button with primary
 * text — the standard Material "white filled button on a coloured app-bar"
 * look, high contrast in BOTH light and dark themes. This makes the
 * style-guide-sanctioned ButtonColor="Color.Surface" header CTA render
 * correctly. The double-class selector (.mud-button-root.mud-button-filled-
 * surface) beats the base .mud-button-filled on specificity, so no !important
 * is required. Theme tokens only — no hardcoded colours.
