Lupine's '(default light theme)' tag had no basis anywhere: the string
exists only in the ThemeType union, and there is no light-default logic
in theme.ts or the Appearance panel. Platform-owner clarification:
Tokyo Night is the sole default (fresh install); the Dark/Light control
is a list filter with per-half counts, not a theme toggle. The page now
says exactly that, keeps the code-verified bits (mode filter opens on
your current theme's half via ThemeModeOf, checkmark indicator, counts)
and states the one-default rule plainly.
