Subject: 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.
