/**
 * Builds the **structural** ECharts option for a pie / donut widget.
 * Mirrors v1's pie look-and-feel: themed legend (`buildLegendConfig`),
 * themed tooltip via `createTooltipPositioner` / `createTooltipFormatter`,
 * `qualitative.bold` color palette, slice borders against the paper
 * background, hover-emphasis disabled, and a centered rich-text label.
 *
 * Layered like Bar / Histogram:
 *   - **Theme-aware bits** live here on a series template (slice border,
 *     center-label rich style sizes, emphasis-disabled).
 *   - **Reactive bits** (tooltip value formatter, center-label text,
 *     selection-driven dim) are re-emitted by
 *     {@link createPieOptionFactory} at fusion time so RelativeData's
 *     percent override flows through.

/**
 * Returns the pie widget's {@link OptionFactory} — one closure that owns
 * BOTH phases of option construction:
 *
 *   - **Structural phase** (`option == null`) — builds the theme-aware
 *     structural option via {@link pieOptions}, optionally merging the
 *     consumer-supplied `optionsOverride` on top. Called once by Provider
 *     to seed `rawOptions` in the store.
 *   - **Merge phase** (`option != null`) — fuses post-pipeline `state.data`
 *     (`PieWidgetData`) into the option via the dataset API. Single-series
 *     → donut (one dataset, `series[i].encode = { itemName: 'name', value: 'value' }`).
 *     Multi-series → horizontal-bar fallback (mirrors v1 pie). Reactive
 *     formatters from `ctx` drive the tooltip + center label at fusion
 *     time so RelativeData's percent formatter flows through without a
 *     structural rebuild.
