/**
* `<lr-knowledge-base-admin>` — a responsive operations shell composing the existing controlled
* source inventory and ingestion queue into one tabbed knowledge-base view. It forwards every
* source/ingestion action under a namespaced event and never creates connectors, uploads files, or
* changes indexing configuration itself. Put configuration controls in the `settings` slot.
*
* 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.
*
* @customElement lr-knowledge-base-admin
* @slot settings - Optional host-owned ingestion, chunking, embedding, or permissions controls.
* @event lr-tab-change - The active operations tab changed. `detail: { tab }`.
* @event lr-activate - Fired on every user activation of an available tab -- a click, or an
*   Arrow/Home/End key -- whether or not `activeTab` actually moved. `detail: { value }` carries
*   the activated tab, the same identity `lr-tab-change` reports. Bubbling and composed, so a host
*   outside the shadow tree receives it. Not cancelable: it is a notification that the user picked
*   a tab, not a veto point, and nothing in this component branches on it. Re-picking the active
*   tab is the case `lr-tab-change` deliberately stays silent for -- "refresh that queue" is a real
*   intent -- and from the keyboard it is otherwise unobservable, because Home on an already-first
*   active tab (or End on an already-last one) activates a tab and produces no click at all. When
*   an activation does move the tab, `lr-tab-change` is emitted first. The normalization that
*   moves an invalid or newly-hidden tab back to Sources is not a user activation and fires only
*   `lr-tab-change`.
* @event lr-source-create - Forwarded source creation request.
* @event lr-source-sync - Forwarded source sync request. `detail: { sourceId }`.
* @event lr-source-pause - Forwarded source pause request. `detail: { sourceId }`.
* @event lr-source-delete - Forwarded source deletion request. `detail: { sourceId }`.
* @event lr-ingestion-retry - Forwarded ingestion retry request.
* @event lr-ingestion-cancel - Forwarded ingestion cancel request.
* @csspart base - The root admin wrapper.
* @csspart heading - The visible heading.
* @csspart tabs - The tablist.
* @csspart tab - One tab button.
* @csspart panel - The active panel.
* @csspart settings - The settings slot wrapper.
* @cssprop [--lr-knowledge-base-admin-tab-selected-border=var(--lr-color-brand)] - Bottom border
*   color of the selected `[part="tab"]`.
* @cssprop [--lr-knowledge-base-admin-tab-selected-color=var(--lr-color-text)] - Text color of the
*   selected `[part="tab"]`. `::part(tab)[aria-selected='true']` is invalid CSS, so this pair is
*   the only way to restyle the active tab without re-pointing the shared brand/text tokens.
* @status stable
* @since 6.2.0
