Agreed, for a public demo like this one, GitHub Pages would work great (or any host that speaks HTTP range requests with CORS). I used R2 partly because I wanted to see how it behaved, and partly because the real use-case doesn't fit Pages. The source data already lives on R2 as Iceberg, the files are per-customer and would probably need auth (signed URLs or a session-checking Worker), and obviously 10k customer cubes on a schedule works better with object PUTs rather than git deploys
