The first tab that actually looks different. Everything here was stock ImGui:
framed collapsing bars, checkboxes with the label trailing on the right, and
sliders glued to the left edge with their name behind them.
Now: section headers with an accent bar, rows with the label on the left and the
control right-aligned in its own column, sliding switches instead of checkboxes,
and a segmented control where two radio buttons used to pretend to be two
settings when they are one.
Three of the four widgets built in this cycle had no call site outside the debug
gallery. That is the exact defect that triggered v1.10.0 -- five tools built and
never wired up -- and the spec rule written afterwards says no widget without a
call site in the same cycle. This closes that on the pilot tab; the remaining
five follow one at a time.
The row helpers live in SettingsWidgets so the other tabs get them unchanged,
and the theme lookups go through SettingsPalette, cached per frame: twenty rows
would otherwise resolve the same five tokens twenty times over.
Section keys are u8 literals rather than the visible titles. ImGui's own storage
keys collapsing headers off the label, which would reset every section's open
state on a language change and merge two sections whose titles translate alike.
Note WindowTab's constructor gained a parameter, so this needs the DI smoke pass
before the next tab follows.
