This directory contains configuration for web applications that come pre-installed on ChromeOS. This includes:

• System web applications (e.g. files app). The logic primarily comes in the form of ash::SystemWebAppDelegate subclasses which provide configuration such as minimum window size, whether to show a tab strip, whether to show the app in the launcher.
• Other UI surfaces powered by by WebUI (e.g. Crosh). The logic primarily comes in the form of content::WebUIConfig subclasses. This is needed to provide static entry points. This logic may also generate some dynamic data to pass to the WebUI.
