Generated Media

• Room backgrounds and imagery: generated with Google's generative AI tools and owned by us under those tools' terms. No stock library or third-party author is involved, so no attribution is owed.
  The source video carried a C2PA Content Credential (digitalSourceType: trainedAlgorithmicMedia, signed by Google Media Processing Services). Re-encoding it for web delivery invalidates that signature by design, so the shipped file no longer carries it — this note stands in its place. Nothing on this site depicts a real person.
