How it works

Each scene is a chunked .luxar.zarr store on object storage. The viewer is deployed once and takes the dataset as a URL — ?src= — so every scene here is the same build pointed somewhere new.

Why it's fast

Cold-load time was dominated by request count, not bandwidth. Re-chunking to a 256 KB target cut objects 9× across this set (387,276 → 43,615) with slightly fewer bytes — bigger chunks compress better.

Delivery

Cloudflare Pages serves the viewer; a Worker streams /data/* and /media/* from R2 on the same origin, so there is no CORS and responses sit in the edge cache. Egress from R2 is free, and cached hits never reach the bucket at all.
