Advanced AI Prompt for Cross-Platform Node.js Build Strategies

Assume the role of a Principal Build Engineer. Create a highly optimized Dockerfile that supports seamless cross-compilation for a Node.js application from a [SOURCE_ARCH] (e.g., amd64 CI runner) to a [TARGET_ARCH] (e.g., arm64 edge device). Utilize Docker's built-in `BUILDPLATFORM` and `TARGETPLATFORM` automated arguments. Explain technically how to handle architecture-specific binary fetches (like esbuild or sharp) for the chosen [NODE_VARIANT]. The resulting multi-stage Dockerfile must be capable of producing a native, optimized image for IoT/edge deployment without resorting to slow QEMU emulation.
