Blink Rendering Engine: Frame, Document, and View Lifecycle

In the Blink rendering engine, LocalFrame, LocalFrameView, and Document form a specialized triad that manages the structure and display of web content. The LocalFrame acts as the primary controller for a browsing context, handling high-level tasks like navigation, security policies, and subsystem management. Underneath this layer, the Document manages the DOM tree and script execution, representing the actual content within the frame. Visual responsibilities, including layout, painting, and scrolling, are delegated to the LocalFrameView, which serves as the rendering interface. This architecture cleanly separates logical frame management from visual presentation and content structure, allowing Blink to handle complex scenarios like out-of-process iframes. The sources further detail how these components are created, linked through garbage-collected references, and systematically destroyed during the detachment lifecycle.
