sys-svc-dns

Bootstrap and maintain DNS prerequisites for your web stack on Cloudflare.

This role validates credentials and (by default) ensures:

• Wildcard A/AAAA records (*.parent) for parent hosts via sys-dns-wildcards (no base/apex records)
• (Optional) CAA records for Let’s Encrypt (kept as a commented block you can re-enable)

Runs once per play and is safe to include in stacks that roll out many domains.

---

What it does

1. Validate CLOUDFLARE_API_TOKEN is present (early fail if missing).
2. Ensure wildcard parent DNS exists (*.parent derived from children):
   • Delegates to sys-dns-wildcards
   • Creates A (and AAAA if enabled) wildcard records on the Cloudflare zone, optionally proxied.
3. (Optional) CAA records for all base SLDs (commented in the tasks; enable if you want CAA managed here).

Parent hosts example:
c.wiki.example.com → parent wiki.example.com (plus example.com apex)
