# Rooftop City Source Art

Generated with the built-in image generation tool. The selected PNG originals
are preserved in this directory; the offline packer prepares runtime atlases.
The city itself is MASM world-space geometry, not a generated city background.

## Prompt Set

- `rail-hands-v1.png`: transparent eight-pose sprite sheet, two anatomical hands
  and complete forearms reaching forward and resting naturally on a low rooftop
  handrail, first-person view, dark sleeves, consistent camera and anatomy.
- `city-facades-v1.png`: eight detailed, straight-on Petersburg-inspired
  classical building facades, varied pastel masonry, carved window surrounds,
  cornices and realistic windows; no perspective, sky or ground.
- `modern-facades-v1.png`: varied straight-on contemporary glass, brick,
  townhouse and civic building facades, suitable for wrapping real geometry.
- `roof-zinc-v1.png`: detailed weathered blue-grey standing-seam zinc roof
  surface, evenly lit, seamless material texture, no building silhouette.
- `sunset-sky-v1.png`: panoramic sunset sky with fine pink and warm cloud
  streaks fading into cool blue; no buildings, landscape or city silhouette.
- `night-sky-v1.png`: panoramic deep night sky with subtle clouds and stars;
  no buildings, landscape or city silhouette.

These record the asset specifications. The generated images are originals,
not an exact reconstruction of any real venue or skyline. Alpha cleanup,
optical-flow in-betweens, window masks, light maps and mesh generation are
deterministic offline processing; no image service is used by the game.
