/**
 * @module flint-chart/echarts
 *
 * ECharts backend for flint-chart.
 *
 * Compiles the core semantic layer into ECharts option objects.
 * Contains EC-specific assembly, spec instantiation, and chart templates.
 *
 * Architecture contrast with Vega-Lite backend:
 *   VL: encoding-channel-based — { encoding: { x: { field, type }, y: ... } }
 *   EC: series-based           — { series: [{ type, data }], xAxis, yAxis }
 *
 * Same core pipeline (Phase 0 + Phase 1), different Phase 2 output.
