blink::Page

the page container and animation clock keeper. Page holds frame trees and the PageAnimator that services script‑driven animations on each tick. It’s the top‑level context for the document/view that WebFrameWidgetImpl coordinates with. You see it pulled into the document and frame code paths whenever lifecycle‑wide actions are taken.
