T33: the sessions and right columns resize by a drag on their border toward the terminal, 160 to 960 pixels, kept in the settings once a drag rests; Ely 5c2822c's resizable ShellColumn, whose handle occludes the header so the drag moves no window, and Ely 005faef's handle line, a filled hairline, since gpui paints a border no wider than half its box
