"""Bố cục khung chat — R08-T06.
Hai cột: mạch hội thoại bên trái, khung tệp đầu ra bên phải. Ô nhập nằm dưới
CẢ HAI cột — đó là lý do khung tệp đứng cạnh mạch hội thoại mà không làm hẹp
chỗ gõ. Đặt trong cột chat thì ô nhập co lại mỗi lần có tệp xuất hiện.
Vài widget cố ý được gắn vào một cha ẩn vĩnh viễn thay vì bỏ hẳn: khung tệp
đầu vào và bảng kế hoạch cũ vẫn còn được gọi ``set_steps``/``add`` ở nơi
khác. Không có cha thì lần gọi đầu tiên sẽ bật lên thành một cửa sổ nổi lạc
lõng giữa màn hình.
Cùng kiểu mixin, xem ghi chú ở đầu ``presentation/shell/nav_rail.py``.
