Cross-cloud App Splitting With WebAssembly Components

Claim: one codebase compiles to WebAssembly and is split at deploy time so pieces run in different Kubernetes clusters, clouds, or edge locations. Uses Rust and TypeScript, the CNCF tool Spin, Helm and SpinKube to turn ~a dozen independently compiled Wasm components into a CMS demo (QR generator, front end, repo, admin). Demo runs locally end to end and deploys split across clusters; component sandboxes reduce boilerplate and surface-area for ops, though the component model is still maturing.
