/**
 * Chart.js chart assembly — Two-Stage Pipeline Coordinator.
 *
 * Reuses the **same core analysis pipeline** as Vega-Lite and ECharts:
 *   Phase 0:  resolveChannelSemantics  → ChannelSemantics
 *   Step 0a:  declareLayoutMode    → LayoutDeclaration
 *   Step 0b:  convertTemporalData  → converted data
 *   Step 0c:  filterOverflow       → filtered data, nominalCounts
 *   Phase 1:  computeLayout        → LayoutResult
 *
 * Then diverges for Phase 2 (Chart.js-specific):
 *   template.instantiate → builds Chart.js config structure
 *   cjsApplyLayoutToSpec → applies layout decisions to config
 *
 * Key structural differences from ECharts / VL output:
 *   VL: { mark, encoding, data: {values}, width, height }
 *   EC: { xAxis, yAxis, series: [{type, data}], tooltip, legend, grid }
 *   CJS: { type, data: { labels, datasets[] }, options: { scales, plugins } }
 *
 * This module has NO React, Redux, or UI framework dependencies.
