## Guardrails

- Production domain must be explicitly confirmed before deploy or SEO work; never infer it from repository files, comments, staging URLs, or old audits.
- Keep claims tied to accessible first-party evidence such as datasheets, certificates, and test reports.
- Do not commit credentials, tokens, or private logs.
- Treat production 404 behavior, Cloudflare crawler policy, image dimensions/CLS, and Product schema offers as separate follow-up work.
