The bootstrap script previously fell back to the OS color-scheme
preference and left font-scale unset until the user picked one. For
admin work — dense tables, lots of small text, monitoring dashboards —
dark + sm is the better starting point and matches what most operators
end up choosing anyway.
Users who've already picked a theme/font keep their stored preference;
this only affects fresh sessions where localStorage has no value yet.
