* @module data-transformers/content-generators/dashboard-section
* @description Generates embeddable Chart.js dashboard sections and CSS-only
* multi-panel dashboards that can be injected into any article type via the
* `TemplateSection` extensibility pattern.
*
* Agentic workflows call `generateDashboardSection()` (single-chart) or
* `generateMultiPanelDashboardSection()` (multi-panel AI-driven) with chart
* configurations sourced from MCP servers or CIA-data and append the returned
* `TemplateSection` to the article's `sections` array.
*
* The generated HTML includes:
* - One `<canvas>` element per Chart.js chart (config in `data-chart-config`)
* - CSS-only heat maps (no JS required) for stakeholder impact matrices
* - CSS-only gauge dials for coalition stress / confidence indicators
* - Optional data tables for accessibility (screen-reader fallback)
* - ARIA labels and roles throughout for WCAG 2.1 AA compliance
*
* Client-side Chart.js chart initialisation is NOT performed automatically by
* this module. Embedding pages MUST load Chart.js and run an initializer (for
* example, a shared `chart-factory.ts` or any loader that scans canvases for
* `data-chart-config` and calls `createChart()` or equivalent).
*
* **Dependencies** (loaded by the Vite build from `package.json`):
* - chart.js ^4.5.1
* - chartjs-plugin-annotation ^3.1.0

* Generate an embeddable multi-panel AI-driven dashboard section.
*
* Returns a `TemplateSection` containing a responsive grid of panels, each
* of which may contain a Chart.js chart, a CSS-only heat map, or a CSS-only
* gauge dial, plus AI-generated interpretation text and confidence indicators.
* Cross-panel AI insights are rendered at the bottom.
*
* Accessibility: every chart canvas carries `role="img"` + `aria-label`;
* heat maps use `role="table"` with row/column headers; gauges use
* `role="figure"` + `aria-label`; confidence bars use `role="meter"`.
*
* @example
* ```ts
* const section = generateMultiPanelDashboardSection({
* data: {
* title: 'Coalition Stability Monitor',
* summary: 'AI-driven analysis of current coalition dynamics.',
* layout: 'grid-2x2',
* panels: [

* title: 'Political Alignment',
* chart: { id: 'alignment-chart', type: 'radar', title: 'Party Positions', labels: ['Economy', 'Security'], datasets: [{ label: 'SD', data: [80, 70] }] },
