A synthetic 2 x 2 panel detector, its panels turned 0/180/90/-90 degrees, recorded twice: assembled
with the gaps masked, and stacked one panel under the other with the DetectorModules that place them -
the same value in every physical pixel. What is already layout-correct runs as [PanelLayout]: the
panel table itself, spot centroids on the plane through SpotAnalyze, and predictions going plane ->
panel -> Bragg engine -> plane.
The equivalences the next stages have to deliver are hidden cases tagged [PanelLayoutTodo], failing
today: the azimuthal-integration map and the resolution mask per stored pixel (stage 1), Bragg
integration measuring the same intensity (stage 2), and spot finding that never joins two stacked
panels (stage 3). A stage that makes its case pass retags it [PanelLayout].
