You're seeing this page because…
…the CDK stack deployed and CloudFront is serving the bundled placeholder. If you can read this, the “hard” parts of the setup are already done: Route 53 delegation, ACM cert, CloudFront distribution, the URL-rewrite Function, the bindle wiring, and (assuming you're past Phase 5) CloudFrontSigner.

Edit the file on disk and re-publish:
vim assets/index.html # or your editor of choice ./scripts/publish.sh # syncs assets/ to S3 + invalidates CloudFront
For new sub-sites, drop a directory under assets/:
