/**
 * Plotly template registry.
 *
 * Mirrors the structure of chartjs/templates/index.ts, echarts/templates/index.ts
 * and vegalite/templates/index.ts but with Plotly template definitions.
 *
 * Coverage: the four original acceptance templates (Bar, Line, Area, Scatter)
 * plus an expressive tranche mirroring most of the Vega-Lite catalog (grouped/
 * stacked bar, distributions, circular charts, specialized native-trace charts),
 * two Plotly opportunity charts (Funnel, Gauge) that showcase native
 * `indicator`/`funnel` traces ECharts otherwise hand-builds, native geo charts
 * (Map, Choropleth — Plotly's own `scattergeo`/`choropleth` built-in atlas, no
 * TopoJSON fetch/join needed), and two composite table/strip layouts
 * (Sparkline, Bar Table) built as self-contained Plotly figures (own axis
 * grid + paper-anchored annotations) rather than forced through the generic
 * cartesian column/row facet combiner (`facet.ts`), which only supports one
 * axis pair per panel. See `sparkline.ts` / `bar-table.ts` for the composite
 * layout technique and `selfManagesFacets` in `../assemble.ts`.
