The surface is a grid that never declared a column, and an implicit auto
column sizes to its items' min-content. The coding status row (branch, PR
chip, worktree path, counts — none of it wrapping) out-measured narrow panes
and silently set the track wider than the surface; every w-full child laid
out against that phantom width and overflow-hidden clipped the right edge,
send button first. grid-cols-[minmax(0,1fr)] pins the track to the surface.
