   RED ASCENDANCY STRUCTURES
   ----------------------------------------------------------------------------
   A separate industrial architecture kit for the Legion/Red Ascendancy. These
   are not recoloured Nova buildings: every family uses squat armored plinths,
   oversized mechanisms, exposed heat hardware and red command-view livery.
   The maps at the bottom deliberately mirror BLD_MDL so old saves keep their
   simulation type while receiving the correct faction silhouette at render.
