// Override any of the `--hub-board-*` design tokens in a single include. Every
// parameter is OPTIONAL and defaults to `null`: only the parameters you pass
// are emitted, so the rest keep the component's defaults. Token-based and
// self-contained (no Bootstrap dependencies).
//
// @example
//
//   @use 'ng-hub-ui-board/styles/mixins/board-theme' as *;
//
//   .sprint-board {
//     @include hub-board-theme(
//       $accent: var(--hub-sys-color-success),
//       $column-bg: #f6f8fa,
//       $card-border-radius: 0.75rem,
//       $columns-gap: 1.25rem
//     );
