## Processing

Each original 1024 × 1024 JPG was resized to **512 × 512** using high-quality
image smoothing and re-encoded as JPEG at quality 88 with `@napi-rs/canvas`.
No crop, recoloring, generated content or painted detail was applied to these
files. Their seamless tiling is retained. The eight files total **388,873 bytes**.

The game may apply lighting, fog and map-specific overlays during rendering.
The existing imported weapon and enemy textures were preserved separately.
