+The first generator used straightforward Blender Python primitives to prove that

+data. That proved the seam, not the final method.

+Primitive stacking is not expressive enough for production illustrated IF
+blockouts. It creates plausible-looking clutter without readable authored
+silhouettes, and it fails quickly on rooms that need clear construction logic,
+nonhuman work affordances, and camera-safe spatial staging. Do not keep adding
+more cylinders to compensate for weak shape language.
+
+Production blockouts should move to authored Geometry Nodes / Geometry Script
+modules or hand-authored Blender kit pieces driven by plan parameters. The plan
+format is shaped for that replacement:
 
 - every procedural organ has a `geometry_script_tree` handle
 - every organ has parameter JSON
