A different layer

See through the ground.

A north-anchored horizon silhouette separates the atmosphere-tinted sky from a dimmed lower hemisphere — so you can keep exploring what is still below the horizon instead of losing half the universe at your feet.

The visible sky follows the Sun continuously from clear daylight blue into the indigo of night.
