Serialisable draw command — a small DSL for the chart’s draw pass that can be replayed on a regular CanvasRenderingContext2D or transferred (via postMessage) to an OffscreenCanvas worker. Charts that want offscreen rendering build a DrawCommand[] and feed it to OffscreenRenderer or executeCommands.
