/**
 * Builds the **structural** ECharts option for a timeseries widget —
 * time x-axis, value y-axis, themed tooltip, themed legend, CARTO color
 * palette. Mirrors {@link import('../bar/options').barOptions} so all
 * four ECharts widgets share v1 look-and-feel.
 *
 * Intentional deviations from bar (timeseries-specific):
 *   - **X-axis is `type: 'time'`** (not 'category'). ECharts handles
 *     uneven sample spacing and zoom-level-aware label formatting.
 *     `labelFormatter` is wrapped so the consumer sees a `Date`, not
 *     a numeric timestamp.
 *   - **Tooltip body reads `{ name, value }` rows**, same as bar, but
 *     the `name` may arrive as `Date | number | string`. The
 *     `labelFormatter` receives a `Date` regardless.
 *
 * Intentionally data-agnostic: no series, no dataset, no `legend.show`
 * (those depend on data and are added by the option factory's merge
 * phase via {@link createTimeseriesOptionFactory}).

/**
 * Returns the timeseries widget's {@link OptionFactory} — one closure

 *
 *   - **Structural phase** (`option == null`) — builds the theme-aware
 *     structural option via {@link timeseriesOptions}, optionally merging
 *     the consumer-supplied `optionsOverride`. Called once by Provider to
 *     seed `rawOptions` in the store.
 *   - **Merge phase** (`option != null`) — fuses post-pipeline `state.data`
 *     (`TimeseriesWidgetData`) into the option via the dataset API: one
 *     dataset per series, each series referencing its dataset by index,
 *     encoded by `name` (x — time) and `value` (y). Mirrors {@link import('../bar/options').createBarOptionFactory}:
 *     series-template merge for `addStack`, reactive formatters from
 *     `ctx`, `niceNum`-rounded y-axis bounds at fusion time, and
 *     `positionDataZoomForLegend` layout for ZoomToggle sliders.
