/**
 * Pure data + types for the dashboard-PDF report's widget catalogue.
 *
 * Lives in its own file so client-side surfaces (the "Export as PDF"
 * dialog) can import the catalogue without dragging the server-side
 * resolver - which imports the DB layer - into the client bundle.
 * Before this split, `export-dashboard-pdf-button.tsx` pulled
 * `PDF_DASHBOARD_WIDGETS` from `dashboard-report-data.service.ts`,
 * whose top-level `import { getKpis } from './dashboard.service'`
 * dragged in `postgres` and crashed the client build with
 * "Module not found: Can't resolve 'fs'".
 */

/**
 * Every selectable widget on the export dialog. Each entry maps 1:1
 * to a section in `dashboard-report.tsx` and a fetcher in
 * `resolveDashboardReportData()`. Categorised so the dialog can
 * render grouped checkboxes (Charts / Tables / Time-period cohorts /
 * Activity & people).
 *
 * Convention: where a widget has both a chart-style and a
 * table-style variant of the same underlying data (pipeline funnel
 * is the canonical case), we expose BOTH ids and let the rep pick.
 * `*_chart` ids render an SVG chart inline; `*_table` ids render
 * the same data as a SimpleTable.
 *
 * Backwards-compat: the legacy ids `pipeline_funnel`, `berth_status`
 * and `source_conversion` remain valid (they render as tables -
 * the original behaviour) so existing saved-templates keep working.
