+"""Shared mapping for the sar3d bottom-view projection choices.
+
+The bottom plot of the sar3d mode projects the imaged volume along a
+horizontal direction rotated around the vertical Y axis: 0° = front view
+(X horizontal), 90° = side view (Z horizontal). One shared mapping keeps the
+combo box, the live-config build, the profile persistence and the plot labels
+consistent.
