arena is a fully static Next.js export. Every page is HTML on disk — there is no Node.js process at runtime, no database, no API hop. nginx serves out/.

"Refresh the dashboard" means "rebuild the container". The sync stage of the Dockerfile re-pulls from Navigara, re-aggregates, and writes a fresh set of data/*.json snapshots. Then next build inlines them into HTML.

In dev: bun run sync writes data/ from the synthetic fixture (no API access needed) or from real Navigara if NAVIGARA_ORG + NAVIGARA_API_URL are set in.env.local.
