Shared Todos

Add, check, and remove todos in the React app — the Svelte app renders a synced list with progress stats.

React Todos ──todos-change──▷ Host ──todos-update──▷ Svelte List

How It Works

1. The React app manages a full todo list with add, toggle complete, and delete
2. On every change, it sends the entire todo array via rpcEmit('todos-change', { todos })
3. The Svelte list receives todos-update and renders items with a progress bar showing completion stats
4. State lives in the React app; the Svelte app is a pure display consumer
