/* Operations Centre (/operations-centre) — see AI.Client/Pages/OperationsCentre/OperationsCentre.razor.
   Global stylesheet per house convention: *.razor.css is inert in this project, and Blazor's ::deep
   combinator only exists for scoped CSS, so it can never match here — every selector below is a plain
   descendant selector.
   The header time-range control (.ops-controls / .range-seg) renders inside <PageHeader>, which is a
   sibling of the .operations-centre body div, NOT a descendant — those rules are intentionally NOT
   prefixed with .operations-centre. */

/* Every token below resolves from the house --mud-palette-* / --status-* variables rather than a literal
   hex, so this page holds correctly in light, dark AND the red tenant-operator theme without a
   `.mud-theme-dark` fork — the web host never stamps that marker class (MudThemeProvider only swaps
   the palette variables), so a class-scoped dark override here would silently never fire. Severity
   tones (success/warning/error/info) intentionally use --status-*-hue rather than --mud-palette-error
   etc., matching utilities.css: severity means the same thing in every theme and does NOT follow the
   tenant-red repaint, only genuinely actionable/selection colour does (--mud-palette-primary). */
