Add common public security headers
Why this needs attention
Several basic browser protection headers were not visible.
These headers reduce avoidable browser-side risk and show a baseline of care before launch.
Recommended correction
Evidence
Detected 0 of 5 common public security controls. Present: none. Missing: strict-transport-security, content-security-policy, x-content-type-options, frame protection (x-frame-options or content-security-policy frame-ancestors), referrer-policy.
Priority
Priority 5: fix before sharing the page publicly.
Fix Prompt

Low contrast makes a launch page feel less polished and can exclude users with low vision.
Recommended correction
Evidence
5 of 100 rendered text color sample(s) missed WCAG contrast targets. Worst rendered ratio: 4.24.

Ready combines robots policy, a bounded synthetic User-Agent fetch, indexability, and snippet eligibility. Synthetic probes do not prove vendor-origin traffic. Purple preference states are training or data-use choices and do not lower the AEO score.
The image refreshes from FreeScan after a completed rescan. Clicking it always opens the newest public report saved for this exact scanned URL.
Scan evidence is included as untrusted data. The implementation brief instructs agents to verify findings before editing and to avoid destructive or speculative changes.
