The shell is MaxHeight 700 and the settings panel had grown past it with no ScrollViewer,
so everything below roughly the transition section was unreachable. That is why 'Tablet
(Horizontal Rectangle)' existed in the XAML and in the model but never appeared in the app:
the shape control itself was cut off, not the option.
Panel row is now * with an Auto ScrollViewer, so every section is reachable and the next
one added cannot silently fall off the bottom.
