boot with a single shell pane (was three). Options.shells (default 1; >=3 gives the classic two-column boot), -n <count> CLI flag. The 26 legacy snap scripts pin -n 3 on their start line so their coordinates and goldens stay valid; boot.snap tests the new default (golden regenerated: one full-width pane). 28/28 green.
