/**
 * Builds the **structural** ECharts option for a scatterplot widget — both
 * axes `type: 'value'` (not category, unlike Bar/Histogram), grid, tooltip
 * triggered per-item rather than per-axis. Intentionally data-agnostic: no
 * series, no dataset, no `legend.show` (those depend on data and are added
 * by {@link createScatterplotOptionFactory}).
 *
 * Styling parity with v1: dark themed tooltip via `createTooltipFormatter`
 * + `createTooltipPositioner`, `buildGridConfig`-based grid, polished
 * axisLine/Tick/splitLine, `overlineDelicate` axis labels, structural
 * legend wired via `buildLegendConfig` (toggled by the merger), and the
 * CARTO `qualitative.bold + secondary` palette — same pattern bar /
 * histogram / pie already use. {@link createScatterplotOptionFactory}
 * wraps this builder in its structural-phase branch.

/**
 * Returns the scatterplot 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 scatterplotOptions}, 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`
 *     (`ScatterplotWidgetData`) into the option via the dataset API. Each
 *     series's `[x, y]` tuples land in `dataset[i].source` as 2-column
 *     rows; the series uses positional encoding (`encode: { x: 0, y: 1 }`)
 *     and `type: 'scatter'`. niceMin/niceMax are computed over both axes
 *     so the chart frames data on rounded extents and numeric jitters
 *     don't shift gridlines per render. Reactive `ctx.formatter` (driven
 *     by RelativeData) re-derives the y-axis label and tooltip at fusion
 *     time; `xFormatter` stays baked at structural-build time (relative
 *     is a values-axis concept; x is coordinate-space).
 *
 * When `ZoomToggle` installs a `dataZoom` slider, grid bottom is
 * extended and the slider is positioned above the legend row (if any) —
 * same layout dance bar / histogram / timeseries do.
