                        The striping sits on this wrapper: the rows share their parent with the
                        introduction and the occasional alert, which would shift the parity.

                                        Everything but the settings button switches the tool, so aiming for the
                                        small switch is optional. The button spans that part of the row, which
                                        keeps the settings button outside of it without any event plumbing.

                                                A checkbox rather than a switch, because this row is one entry of a set the
                                                user picks from, not a setting of its own -- the same question the data source
                                                selection next to it asks, and it should not look like a different one.

                                                The checkbox only shows the state; the surrounding button does the switching.
                                                It therefore takes no pointer events at all: its label reaches past the visible
                                                box and would otherwise swallow the clicks landing in that strip.
