What the editor's Next answers: the "New reel" handle the edge opens. The type is
written out because the reel mode closes the editor before it opens the sheet, and
the compiler's inference of an action that both closes a frame and answers an
edge's handle makes the launch's screen union exceed the
declaration-serialization limit (the same wall the named
PostingCameraScreenDefinition exists for). The effect's own type is the edge's,
with the services the reel mode's preparations add.
