3) Snippet rules

• iframe src must point at /seller-fees/embed/… (frame-allowed). Full hubs / compare are X-Frame-Options: DENY.
• Attribution — every embed footer already includes “KEEP fees via realratecalc.com”. Keep height tall enough that it stays visible.
• No new soft CTAs — do not inject Impact URLs around the iframe.
• Math lock — embeds copy hub #out / fee-index only. No invented fees.
