Browser debugging

Build with the default sourcemap and inspect the generated bundle in browser developer tools. Check the console for build/runtime errors, the Network tab for the static bundle and WebSocket upgrade, and Application storage for IndexedDB saves.

For a WebSocket deployment, verify that the proxy preserves HTTP/1.1 upgrade and Upgrade/Connection headers. Confirm that the client uses ws: for HTTP and wss: for HTTPS, and that the relay is running at the configured endpoint.

When inspecting derived Automerge state, materialize the proxy before using object enumeration:

const plain = JSON.parse(JSON.stringify(state));
const values = Object.values(plain.tokens);

If a build fails, first run the exact entry/output command again and check the entry imports and installed dependencies. The WASM is expected to be in the bundle; a missing separate .wasm request is normal for this build path.
