/*
  Starruk.Platform.Blazor.Components — MultiSelectFilter popover styling.
  Consumers add this stylesheet once:
    _content/Starruk.Platform.Blazor.Components/starruk-multiselect-filter.css

  MultiSelectFilter's dropdown/popover markup wasn't part of the shared-kit CSS
  Starruk.Platform.Blazor.DesignSystem ships (PageHero/cards/filter-bar/states/tables only, per
  ADR-006 §6 in that package) — this component styles its own class names here rather than
  duplicating anything DesignSystem already owns. Reads --mud-palette-* runtime vars (populated by
  whatever MudTheme the host registers) and --s-secondary for the selected-item tint, so it still
  tracks the registered Starruk palette without redefining brand colors.
