/**
 * Bun server: HTML import (bundles src/app.js + src/style.css and everything

 *
 * This rebuild ships direct-connect only: no /api/session load-balancer
 * proxy (that needs backend credentials this rebuild doesn't have). Point
 * Settings -> "Direct server URL" at a running s2s realtime endpoint
 * (ws://.../v1/realtime) to talk to it.
