summary
Claim: wasmCloud plus WebAssembly components untangles boilerplate into reusable building blocks. Demo builds a file/CRUD blob actor called Blobby (254 lines) and swaps runtimes and providers live to produce four different apps from the same component, including a Vault-backed encrypted store and a local HTTP server. Original minimal Go counter had nine dependencies; the componentized version runs with 254 lines of code, supports no redeploys configuration changes at runtime, and all live demos work as shown.
