/**
 * @module flint-chart/excel
 *
 * Excel backend for flint-chart.
 *
 * Compiles the core semantic layer into a native Office.js Excel chart spec
 * (a wide/matrix data range + chart type, axes, legend). A host renders it via
 * the Office.js Excel API (`sheet.charts.add(...)` + `chart.getImage()`).
 *
 * Architecture contrast with other backends:
 *   VL:    encoding-channel-based — { encoding: { x, y }, mark }
 *   EC:    series-based           — { series: [...], xAxis, yAxis }
 *   CJS:   dataset-based          — { type, data: { labels, datasets } }
 *   Excel: range/matrix-based     — { chartType, data: [[...]], seriesBy, axes }
 *
 * Same core Phase 0 (semantics); Excel-specific Stage 3 output.
