Refactoring for API Speed — a single-user app should boot in milliseconds, not a minute

Refreshing the page takes 60s+ for the logged-in workspaces to appear, and every microfrontend/microservice hop adds latency waiting for the others to respond or 'acknowledge' each other. There is ONE user. The distributed mesh — 7+ Railway services, per-remote WebSockets, NATS request/reply, a remote cloud DB, a separate auth service — imposes coordination cost that dwarfs the actual work. This is the diagnosis and the refactor design space, measure-first.
