## Subscription router: `subscription-router.ts`
Associates messages from the backend with subscribers in the frontend, and routes messages to subscriber callbacks. This module provides a `subscribeJsMessage(messageType, callback)` function which JS code throughout the frontend can call to be registered as the exclusive handler for a chosen message type. This file's other exported function, `handleJsMessage(messageType, messageData, wasm, instance)`, is called in `editor.ts` by the associated editor instance when the backend sends a `FrontendMessage`. When this occurs, the subscription router delivers the message to the subscriber for given `messageType` by executing its registered `callback` function. As an argument to the function, it provides the `messageData` payload transformed into its TypeScript-friendly format defined in `messages.ts`.
