Long text in the chat field gets the full width

When you write or dictate a longer message in the field under a conversation, the screenshot, microphone and Send buttons now stack in a narrow column at the bottom right instead of sitting side by side. The text gets the width they free, which on the phone means noticeably more words per line and less scrolling. Short text keeps the buttons side by side as before, and the switch between the two layouts happens without jumping back and forth while you type, delete or dictate. The placeholder stays fully readable, and the thin scrollbar that used to show beside the buttons is gone. This applies everywhere the field appears, on the phone and on the desktop.
