## 5. Anti-fabrication safety rules (non-negotiable)

A landing page is a public marketing claim; fake proof is a legal and trust liability (false advertising, FTC-style endorsement rules in the US, comparable EU consumer law).

- **Logos, testimonials, names, photos, ratings, customer counts, and performance metrics MUST be real and supplied/approved by the user.** Never invent a brand logo, fabricate a quote, attach a stock photo to a made-up person, or write "Trusted by 10,000+ teams" / "40% faster" without a real source.
- If the user has **no proof assets yet**, do **one** of:
  1. **Delete** the proof section entirely (a missing section beats a fake one), or
  2. Insert an **obvious placeholder** the user must replace, clearly marked — e.g. `[PLACEHOLDER: replace with real customer logo]`, `[TESTIMONIAL — get written permission before publishing]`, `[METRIC — cite real source]`. Never let a placeholder read as a finished claim.
- **Comparison/superlative claims** ("the fastest", "#1", "best") need substantiation — flag them for the user to verify or soften to defensible language.
- **Regulated claims** (health outcomes, financial returns, "secure"/"compliant", "GDPR/SOC 2/HIPAA") must reflect the user's *actual* certifications. Don't print a SOC 2 badge they don't hold. Flag for legal review when in doubt.
- Star ratings/review counts must match the real profile and ideally **link** to the source (G2, Trustpilot, App Store).

State explicitly in your handoff which items are placeholders awaiting real assets.
