@title Floating button over a list
@brief A floating child stays pinned while the list behind it scrolls.
The panel is a scrollable list of buttons. The round "+" button sets
`floating="true"`: a floating child is ignored by the layout and is not
moved when its parent scrolls, so it stays anchored to the bottom-right
corner while the list slides underneath it.
