/**
* `<lr-rag-eval-dashboard>` — a controlled RAG quality overview with current metric cards,
* per-metric trends, evaluation slices, and run history. It displays host-computed metrics and
* never executes datasets, retrieval, judges, or model calls. A controlled `slice` absent from
* the current runs is preserved and renders an explicit localized unavailable-filter state;
* the component never silently switches it to All.
*
* Public collection properties take bounded, clone-owned readonly snapshots. Create a new
* collection and reassign it after changes; mutating the assigned array does not update the view.
* Blank metric/run ids and later duplicates are ignored before fallback selection, filters,
* counts, rendering, or actions. The first record for an id wins.
*
* @customElement lr-rag-eval-dashboard
* @event lr-metric-change - A metric was activated. `detail: { metricId }`.
* @event lr-slice-change - An evaluation slice was activated. `detail: { slice }`.
* @event lr-run-change - An evaluation run was activated. `detail: { run }`.
* @csspart base - The named dashboard region.
* @csspart heading - The visible dashboard heading.
* @csspart slices - Slice filter controls.
* @csspart slice - One slice filter.
* @csspart slice-selected - The controlled active slice.
* @csspart metrics - Metric-card controls.
* @csspart metric - One metric control.
* @csspart metric-selected - The controlled active metric.
* @csspart metric-category - The metric's caller-supplied category label.
* @csspart chart - The active metric trend.
* @csspart runs - Evaluation run history.
* @csspart runs-heading - Run-history heading.
* @csspart run - One evaluation run.
* @csspart empty - The no-runs or unavailable-controlled-slice state.
* @cssprop [--lr-rag-eval-dashboard-selected-border-color=var(--lr-color-brand)] - Border color
*   shared by the controlled active slice and metric.
* @status stable
* @since 7.0.0
