Delivered surface maps are 4096 x 2048; the ring strip is 4096 x 32.

The voyage is an artistic composition, not a scale solar-system simulation.
Lighting and atmospheric grading are applied in the renderer.
Chapter preview images are renders of these credited assets.

Lunar relief: NASA Scientific Visualization Studio / LRO LOLA, ldem_16_uint.tif.
https://svs.gsfc.nasa.gov/4720/
Converted to a 4096 x 2048 linear grayscale WebP; normalized elevation range,
lightly filtered to limit quantization at the terminator. Relief affects lighting;
the silhouette retains the authored sphere for camera-clearance guarantees.

Celestial surface refinement (2026-09-10)
The current stellar photosphere, comet, asteroid shapes and galactic light/dust
are procedural illustrations. The legacy Sun texture remains in this asset
folder but is no longer loaded by AETHER. Loading previews combine the credited
planetary maps above with these procedural scenes.
