Ten .fitzv components compiled to WebAssembly with
fitz build --target wasm-client, in a single bundle. Each
one owns its state in Rust inside the WASM instance. It all runs in
the browser — no server, no WebSocket.
If you see this text but not the components, either the WASM bundle
failed to load (check the DevTools console) or the page was opened over
file://. ES modules need an HTTP origin: serve with
python -m http.server 8000 or equivalent.
