+/// Home screen rather than a centred Material icon, which means they are made of
+/// fixed-width rows — the hub rail on slide 1 is a dozen sized children in a
+/// single unflexed `Row`. That is exactly the shape that overflows on a narrow
+/// phone, so every slide is laid out at the narrowest screen the app supports.
