	Renders svgBytes into a caller-provided RendererInterface via the sandbox child + host-side ReplayingRenderer. The child's wire stream is decoded into target — after this call returns with kOk, the target has received beginFrame(), a sequence of drawing calls, and endFrame(), same as if the driver had run in-process.
RenderResult	render (std::string_view svgBytes, int width, int height)
	Convenience wrapper: renders via renderToBackend into a host-side Renderer and encodes the snapshot to PNG. Preserves the S1 public contract so existing callers (tests, CLIs) don't have to change.

Detailed Description

Spawns and communicates with the sandbox child binary. Not thread-safe: construct one instance per thread that needs to render.

Constructor & Destructor Documentation

◆ renderToBackend()

RenderResult donner::editor::sandbox::SandboxHost::renderToBackend	(	std::string_view	svgBytes,
		int	width,
		int	height,
		svg::RendererInterface &	target )

Renders svgBytes into a caller-provided RendererInterface via the sandbox child + host-side ReplayingRenderer. The child's wire stream is decoded into target — after this call returns with kOk, the target has received beginFrame(), a sequence of drawing calls, and endFrame(), same as if the driver had run in-process.
