Chromium changes: https://chromium.googlesource.com/chromium/src/+/4f22c9c8d3976fc7ccae881d2645dfb480fd46dc commit 4f22c9c8d3976fc7ccae881d2645dfb480fd46dc Author: Anton Goncharenko <agonch@google.com> Date: Wed Feb 11 06:12:57 2026 -0800 [Signin][Android] Migrate NTP Avatar to the activity-less sign-in flow. This is part of the effort to reduce reliance on SigninAndHistorySyncActivity by sign-in entry points. BottomSheetSigninAndHistorySyncCoordinator is instantiated in IdentityDiscController#setProfile, if it's a regular profile (not off-the-record). It gets destroyed if switched to incognito profile. In incognito the profile avatar button should be disabled, but as extra reassurance the sign-in flow crashes with an incognito profile. IdentityDiscController#onClick triggers the new flow via the coordinator when available, falling back to the legacy activity-based flow otherwise.
