/**
 * Prompt panel for the enterprise grid's AI Toolkit. Mount it beside a grid and
 * set its `grid` property: it sends a natural-language prompt through the grid's
 * {@link ApexGridEnterprise.runPrompt} (the built-in rule engine, plus any
 * {@link ApexGridEnterprise.aiReasoner}), then shows what changed with a one-click
 * **Undo**, or the answer in ask mode.
 *
 * Two container modes via `mode`: `'inline'` renders in place; `'dialog'` (the
 * default) is a floating, draggable panel. The element holds no API key and never
 * imports an LLM SDK: it only calls the grid, which owns the reasoning.
 *
 * @element apex-grid-ai
 *
 * A **source badge** shows whether each result came from the deterministic rule
 * engine or an LLM reasoner; **Preview** dry-runs the prompt through
 * {@link ApexGridEnterprise.previewPrompt} (nothing is applied) so the planned
 * steps can be inspected first; and a **transcript** logs past turns.
 *
 * @fires apex-ai-result - After a prompt resolves: `{ result }` (the {@link AIResult}).
 * @fires apex-ai-closed - When a dialog panel is dismissed.
 *
 * @csspart panel - The panel container.
 * @csspart header - Dialog header (drag handle + title + close).
 * @csspart close - Dialog close button.
 * @csspart body - The prompt + result body.
 * @csspart mode-button - A Control / Ask mode toggle button.
 * @csspart input - The prompt textarea.
 * @csspart send - The send / cancel button.
 * @csspart preview-button - The preview (dry-run) button.
 * @csspart result - The result region (applied summary or answer).
 * @csspart abstention - The region shown when the prompt could not be mapped.
 * @csspart preview - The preview region (planned steps, not applied).
 * @csspart source - The badge naming the reasoner that produced a result.
 * @csspart undo - The undo button (control mode).
 * @csspart warnings - The notes / warnings list.
 * @csspart notice - The thinking / empty notice.
 * @csspart error - The error message.
 * @csspart history - The transcript region.
 * @csspart history-item - One past turn in the transcript.
 * @csspart clear-history - The button that clears the transcript.
