Fireproof stores data locally and encrypts it before sending it to the cloud. This demo uses
Netlify Edge Functions, but you can easily run Fireproof on S3 or another provider. You also
accelerate sync times by using a real-time adapter like PartyKit or WebRTC, this demo polls
the server every 3 seconds.
