Static landing page for ctot.dev — the development/testing environment for Inbox by TrueDialog (programmatic transactional email for AI agents).
Served via GitHub Pages; custom domain ctot.dev (apex) is set in CNAME.
DNS for the zone lives in the private Cloudflare Terraform repo
(apex A/AAAA → GitHub Pages, DNS-only). Content is a single self-contained
index.html. Purpose: give the AWS SES production-access review a coherent,
real page behind the sending domain (TD-735).
