<Instructions for building exactly this>

Build a Cloudflare Worker that:
- Uses Email Routing catch-all to send all mail for your domain to the Worker.
- Stores incoming emails in Workers KV under the local part before @.
- Expires stored emails after 2 minutes.
- Exposes GET /latest/<user> to return the latest email sent to <user>@your-domain.
- Returns compact JSON: to, from, subject, body, otp, receivedAt.
- Parses email bodies with postal-mime.
- Extracts numeric OTPs with regex first, then uses a Workers AI binding only as fallback.
- Generates public example addresses from the EFF large Diceware wordlist plus a 6-character lowercase alphanumeric suffix.
- Configures a WAF rate limiting rule for /latest/* at 5 requests per 10 seconds.
- Deploys the Worker on a custom domain and routes Email Routing catch-all to it.

Cost note: exact invoice-matched cost is not exposed here. Cloudflare Billing has a Billable Usage dashboard/API for account-level overage costs, Workers GraphQL analytics can report requests and CPU time, Workers AI reports neuron usage, and Email Routing inbound is unlimited; Email Routing Worker processing is billed as Workers compute.
