Claim: WASM and Docker complement each other — Docker now hosts WASM images on DockerHub and runs WASM containers side‑by‑side with Linux/Windows containers using containerd shims. Examples: Shopify, AutoCAD and Figma Cloud use WASM for heavy client compute; WASM delivers 80–90% native speed with sandboxed IO and fast startup. Practical pieces: three runtimes mentioned (WasmEdge, Wasmtime, etc.), a shim model to plug any runtime, and docker pull/push to DockerHub for WASM images.
