/* ── Simulazione prenotazione ─────────────────────────────────────────────
   One stylesheet for the whole workspace (BookingSimulationWorkspace and its
   Simulation* tabs): the markup spans several components and several MudBlazor
   ones, which scoped CSS would only reach through ::deep. Every class is
   prefixed sim- (workspace) or tt- (time slider), so nothing leaks. Colours are
   the theme's --mud-palette-* (MainLayout.razor), never literals, except the
   brand-green tints, which the palette does not publish. */
