B1: WebContents: The Foundation of Chromium Tabs

The text thoroughly analyzes the foundational structure of Chromium's architecture, which controls the browser window and tab strip elements. This system relies on a central Browser class acting as the controller, coordinating with the TabStripModel to manage the lifecycle and state of individual tabs (WebContents). To maintain cross-platform compatibility, the Browser interacts with an abstract BrowserWindow interface, allowing for different visual implementations like the desktop BrowserView or platform-native code. Through extensive use of the Observer Pattern and delegate interfaces, this design ensures a strict separation of concerns, where the TabStripModel acts as the authoritative source of tab information. This architecture allows the core logic to efficiently translate user commands into content actions and update the view consistently across supported platforms.
