+### SMTP relay DNS requirements (homelab)
+
+When pointing the form at a homelab SMTP relay (Postfix, Mailcow, etc.), the
+relay itself must have proper DNS records or mail **will** land in recipients'
+spam folders — this is the relay's responsibility, not the site's. Ensure the
+sending domain (the host part of `SMTP_FROM`, or the relay's HELO name) has:
+
+- **SPF** (`TXT` on the domain): lists the relay's IP as an authorized sender.
+- **DKIM** (`TXT` on `selector._domainkey`): signs outgoing messages so the
+  relay's identity can be verified.
+- **DMARC** (`TXT` on `_dmarc`): tells receivers how to handle SPF/DKIM
+  failures (start at `p=none` to monitor, tighten to `quarantine` later).
+- **rDNS / PTR** on the relay's public IP: must match the relay's HELO name.
+
+`SMTP_FROM` should use a domain you control (e.g. `no-reply@gregkilmer.com`),
+not `gmail.com` — SPF on a domain you don't own will reject or sink the mail.
+
+Test delivery + spam score with [mail-tester.com](https://www.mail-tester.com/)
+(send a form submission to the unique address it gives you).
+
+### Cloudflare Turnstile (bot protection)
+
+The form includes an invisible Cloudflare Turnstile challenge. To enable it:
+
+1. Create a widget at
+   [Cloudflare Turnstile](https://dash.cloudflare.com/?to=/:account/turnstile).
+   Use the **Managed** challenge mode (invisible, no puzzle).
+2. Put the **site key** in `TURNSTILE_SITE_KEY` and the **secret key** in
+   `TURNSTILE_SECRET_KEY` (both in `.env`).
+3. The site key is public and ships to the browser; the secret stays
+   server-side. The API verifies each token against Cloudflare's `siteverify`
+   endpoint before sending mail.
+
+If neither key is set, Turnstile is skipped entirely (useful for local dev —
+the form works without a challenge). The honeypot + per-IP rate limit still
+apply regardless.
+
 Test it:
 
 ```bash
+# With Turnstile configured, this is rejected (no/bad token) with 400:
+curl -X POST http://localhost:4321/api/contact \
+  -H "Content-Type: application/json" \
+  -d '{"name":"Test","email":"test@example.com","message":"Hello there."}'
+
+# Without Turnstile (keys unset), this succeeds and delivers mail:
 curl -X POST http://localhost:4321/api/contact \
   -H "Content-Type: application/json" \
   -d '{"name":"Test","email":"test@example.com","message":"Hello there."}'
 ```
 
+### Anti-scraping
+
+The site applies a layered anti-scraping policy:
+
+- **`public/robots.txt`** allows legitimate search engines (Google, Bing) but
+  blocks known AI training bots (GPTBot, ClaudeBot, CCBot, Bytespider, etc.)
+  and disallows `/api/` and `/contact` for everyone. Note: robots.txt is
+  voluntary; determined scrapers ignore it.
+- **`noindex` on `/contact`**: the contact page emits
+  `<meta name="robots" content="noindex, nofollow">` so it won't be indexed
+  even if a bot reaches it.
+- **Email obfuscation**: the Gmail address is never in the HTML source as
+  plaintext; it's base64-encoded and decoded to a `mailto:` client-side on
+  click. Dumb harvesters that grep for `@` or `mailto:` find nothing.
