 pass. The current `_build_comedy_store_building()` stays as the fallback.*

+      real (3.2:1 vs ~6:1) — the main shape-language deviation; canopy pitch, blade-sign diameter,

 - [ ] Rank the shape-language gaps between the current procedural building and the four scene

       hillside silhouette and the neighbouring hotel/parking mass. Write the top-five fix list

 - [ ] Rebuild the canopy + blade sign as library props or procedural geometry through the assisted
       pipeline (`blender_assets.py inspect` → scripted edits → `audit`/`fit`), keeping the 4,000
       prop-triangle budget; verify against the street/strip concept pairs before committing.
