"""Public client self-service portal at /repair.

Phase 1 scope (no AI yet):
- /repair             Landing page with "Start" CTA
- /repair/new         Multi-step form
- /repair/submit      POST -> creates repair.order via shared intake service
- /repair/thanks      Confirmation with reference
- /repair/lookup_phone  jsonrpc safe partner match (masked PII)

Security:
- Public auth (no login) - the voicemail prompts mention this URL
- Per-IP rate limit on submit (configurable)
- Honeypot + CSRF
- Phone lookup returns ONLY masked name + address slice (never other PII)
- Records created via sudo in the controller; record rules don't apply
  because anonymous users don't have a session

Phase 2+ will add: AI self-check, upsell engine, smart SMS verify,
safety on-call paging, reCAPTCHA v3.
