ImpositionLayoutStatus

"""
Where an imposition spec's sheet geometry came from, and therefore whether it may be put on a press.

enum ImpositionLayoutStatus {
  """
  Computed by the imposing engine against a resolved substrate. Renderable.

  ENGINE
  """
  Rebuilt from the authored pagesUp/scheme/orientation against the component's real substrate size. Renderable.
  """
  SYNTHESIZED
  """
  Rebuilt, but with no substrate to size the press sheet against — the sheet was inferred from the imposed grid. Cell placement and page order are correct; the sheet is a guess. Cannot be imposed until the stock is confirmed.
  """
  PROVISIONAL
  """
  No geometry — the spec carries too little to place a cell. Cannot be imposed.
