Google Search app tests the UI with Material Design 3 components.
The first of the changes is a redesigned bottom navigation bar, where the current page is indicated by a pill that also has nice animations when switching.
The second change is a redesigned settings pages UI with larger headers and new MD3 toggles. Unfortunately, because of the way the app is designed, some pages look mixed (e.g., "hide explicit results"), because they are essentially an embedded web UI.
Also, this redesign does not apply to the assistant settings page.
This is a server-side change spotted in 13.44.10.29.
