Changes: resized and converted to WebP. Orbit maps are 1024 pixels wide;
detail maps are 4096 pixels wide (Uranus and Neptune: source maximum 2048).
Clouds, normal/specular data and Saturn's ring retain lossless pixel data
after the documented conversion/resizing. Venus is shown with its clouds.
The source maps combine real observations with enhanced colours and some
illustrative terrain. Colour-derived bump shading on rocky bodies is an
artistic effect, not measured terrain elevation.

The orbits, sizes, lighting and Polybrand nebula are an artistic composition.
The Sun and eight planets represent the developer’s services.
The Moon maps remain in the asset collection but are not loaded.
The Sun source named 8k_sun.jpg is actually4096x2048; it is not upscaled.
The composition, custom icons, text shaders and interface are original work
for bartoszsergot.com. Desktop and large-type inspiration:
