 * Shared look of PickList (single select) and TagList (multi select), Component/Common/PickList.
 *
 * Global on purpose: both components render inside Blazor.Bootstrap <Modal> (and ModalEventBoundary), so the
 * dialog chrome and table are not reachable from the components' scoped CSS. Everything is namespaced under
 * .picker-modal (set through the Modal's Class parameter) and uses the theme.css tokens.
