 - **Golden-angle filling:** spoke placement uses the sunflower trick, stepping
   by the golden angle along the axis so each new spoke avoids the previous
   radial lanes while still reading as one organic exchange network.

+  and many brace/catwalk paths into shared curve objects, preserving detail

 - **Python as orchestration:** the cylinder layers, region maps, city blocks,
   social-gradient bands, roads, rivers, forests, clouds, and spokes come from
   small tables and named helpers rather than copied object placement.

 ## Current Limits
 
 - The build is a spatial systems study, not final art.
-- The civic surface is a symbolic map-layer world, not a lived city.
+- The civic surface is still a symbolic map-layer world, but the hubward favela
+  now has enough nested structure to read as precarious built habitat.
 - The current whole-Bloom view is less skeletal, but still a study. It needs
   denser horizon city detail and better art-directed lighting before it earns
   the word cinematic without fraud.
