All data sources are keyless and CORS-friendly — no backend, no API keys, pure client-side JavaScript. See info.html for plain-English explanations of every metric on the dashboard.
There's no build step and nothing to install. Open index.html directly in a browser, or serve the folder:
python3 -m http.server 8000Chart.js is the only third-party dependency, loaded from a CDN at runtime. Everything else is hand-written HTML, CSS, and JavaScript in two files. Deployed as a static site on Netlify.
The interface follows the Observation Deck design language — a dark "mission control" theme shared across the wider project family.
