Two surfaces, one dataset
Design references built in React (via in-browser Babel). Both surfaces read the same shared/data.json globals. Recreate them in your target stack — see README.md for the screen → route → component → data map.
Run the previews from a local server — Babel fetches the .jsx files over HTTP, which file:// blocks.
