These parents use srcdoc so the detector can traverse inside and label parent/child.

Simple iframe (third-party)

Should be labeled iframe.

Parent via srcdoc → Child (third-party)

Parent: iframe parent • Child: iframe child

Guardio-like parent (hidden) → Child (third-party)

Parent uses src="./guardish.html" so it’s treated as Guardio-like (hidden), but its child is shown as iframe child.

Open Shadow Root → iframe

Iframe lives inside an open shadow DOM (should show isShadowDOM=Yes).

Deep nest via srcdoc

Outer becomes iframe parent, inner is iframe child.
