  note: >-
    Squarespace origin. The apex returns HTTP 404 with the Squarespace "Website Expired"
    system page - the marketing-site subscription has lapsed. TLS and HSTS are still served
    by the Squarespace edge.

  note: >-
    Squarespace platform address for the same site; still serves the Luminous marketing page.
    Sends Strict-Transport-Security with max-age=0, i.e. HSTS explicitly disabled. This host is
    Squarespace-controlled infrastructure rather than a Luminous-registered domain, so its
    posture is not attributable to the company.

  note: >-
    No CAA record and no _dmarc TXT record are published. DNS is hosted on Google Cloud DNS and
    carries live Google Workspace MX plus Atlassian, Smartsheet and DocuSign domain-verification
    TXT records, so the domain is actively operated even though the public website has expired.
