Every wizard write goes through Panel, which clips to the panel and saturates
its height arithmetic, so no step panics on a small terminal. The bottom row
truncates in cells, so a wrapped message with a multibyte character is drawn
whole. A scrolling list's range is named on its header row, where no item can
cover it. Tests: a multibyte message at every width, wrap bytes vs cells, a
no-panic sweep of every step at 20-100 x 3-20, the first item filling the list.
