// Inline login WebUI in various signin flows for ChromeOS and Chrome desktop.
// Upon success, the profile of the webui should be populated with proper
// cookies. Then this UI would fetch the oauth2 tokens using the cookies.
//
// The authentication is carried out via the host gaia_auth extension because:
// * The page is loaded in a isolated renderer, which is better for security.
// * Gaia endpoints used during sign-in expect a clean cookie jar.
// * It bypasses account consistency and reconciliation.
