 ## How it works
 
-The module is a factory `(ctx) => handlers`. `src/state.js` opens a fresh closure per `createWorker` with the handle tables (`nodes`, `bindings`, `files`, observers, animations) and the `alloc` / `node` / `allocList` helpers. Eight handler slices (`tree`, `style`, `events`, `forms`, `observers`, `animations`, `media`, `platform`) each return an object literal of named handlers that close over the shared state; `src/index.js` composes them with `Object.assign`. Async callbacks (event listeners, `FileReader`, animation `finished`, observer entries) call `ctx.pushEvent(jsonDetail)` to wake a paused `receive()` in the script.

 Adding a handler is one entry in one slice. Nothing else changes.
 
 ## Performance
 
-Per-handler cost is one `postMessage` round-trip between the Worker (engine) and the main thread (handlers): ~0.1–0.4 ms in modern browsers. Plenty of headroom for UI-rate workloads — events, mutations, layout — at hundreds of ops per frame.

 ### Conventions
 
-- **HTTP handlers are yielding host calls.** They return a Promise on the JS side and the runtime parks the coro in `WaitingHostCall` until it resolves — Python sees a sync-looking call that suspends. `gather()`, `with_timeout()`, and `run()` work over them automatically without `await`/`receive()` boilerplate.
-- **WebSocket and SSE use the push-event pattern** (same as `dom`'s `bind_event`). Connections are opened with a `msg` tag; every wire event arrives in Python via `receive()` carrying that tag.
-- **Handles are integer IDs** — store them, pass them, never compute on them.
-- **Options are JSON strings** — `fetch(url, '{"method":"POST","body":"..."}')`. Mirrors `bind_event` and `animate` in `dom`.
-- **All response bodies arrive as strings.** For JSON, parse with `json.loads` (declare the module in `packages.json` if you haven't yet — see [the dom README](../dom/README.md#api) for the import map snippet).
