deployment

this is a little manual for now, I may automate it in future.

1. deploy the project anywhere you choose (e.g. vercel)
2. visit the site, check the Chrome Console, and record the VITE_GROUP_ID value.
3. also set VITE_JAZZ_API_KEY to your email address.
4. add this value as an environment variable to your deployment.
5. restart / re-deploy.
