Every screen deals itself in, every time

The entrance is no longer a one-off on the boot: dealStage re-arms the class at
the funnel every stage change already passes, so the title screen flies its
plaque and buttons in whenever you arrive at it. The sub-menus join in — their
header, content and footer arrive one after the other instead of the panel
dropping in as one slab — and the poster wall deals its three rooms rather than
its list, since a moving child inside a moving parent starts at twice the
offset and reads as a stutter.
