See it before you install it: a one-click read-only demo

You can now explore a live avuru obs without installing anything: one click on "Try the demo" signs you in as a read-only viewer against a running multi-service app, with real data across every module.

• One click, zero setup. A "Try the demo" button on the login page signs a visitor straight in as a read-only viewer scoped to a demo project — no account to create, nothing to install. The rest of the app behaves exactly as it would for a real user; write actions (triage, settings, user admin) simply aren't offered.
• Real data, every module. The demo is fed by the live OpenTelemetry Astronomy Shop — a genuine multi-service application — so the service map, traces, logs, RED metrics, error tracking, service health and energy views all show real, moving data instead of static screenshots.
• Safe by construction. The demo is a single low-privilege identity: the shared password stays server-side (a rate-limited sign-in endpoint), never reaching the browser, and the whole feature is opt-in — a normal install ships no demo user and no demo project. Enable it with auth.demo.enabled.
• Also in this release. The Settings Users tab now opens in place instead of navigating away, so the tab bar no longer disappears; the login wordmark reads Avuru Obs. See the API reference for the new demo sign-in endpoint.
