Is it built?

Run

bun run scan       # refresh site/state.json and regenerate site/index.html
bun run dev        # serve site/ locally (no data refresh)

or through the flake:

nix run . -- --config config.json --data site/state.json

The scanner uses only Bun's built-in APIs (fetch, Bun.file) and the standard library; there are no npm dependencies. Tests run with bun test tests/.
