/**
 * Pre-resolves histogram color rules to XY-compatible color-only rules.
 *
 * The histogram assigns palette colors per-series with an incrementing index
 * (each matching series gets the next color from the palette).
 * The XY chart's bar series always picks index 0 for colorPalette rules,
 * so we resolve palettes here to match histogram behavior.
 *
 * Rules with a direct `color` value are passed through unchanged (with the
 * default valueAccessor applied). Rules with `colorPalette` are expanded into
 * one per-series `equals` rule with the resolved color string.
 *
 * Invalid palette names are silently skipped so that partially-typed values
 * in a CodeEditor do not crash the chart.
