SkyConditions

Everything that decides how bright the sky is, in one panel: BortleSlider and the four switches that drive the same atmosphere shader.

They used to be in opposite corners of the map — the slider bottom right, the switches at the bottom of the layers list bottom left — and Air & sky glow, by the layers panel's own note, simply overrode the slider 1200px away. Two controls for one quantity, arguing across the width of the screen.

Live render. The engine is not running here, so the naked-eye limit stays blank and nothing reaches the shader.

Air & sky glow Ground Milky Way Twinkling

Turning Air & sky glow off removes the haze, the extinction and the Earth together — the slider above stops applying, and you see the whole celestial sphere at once.

The switches share one binding table and one storage key with LayersPanel — see src/design/compositions/sky-layers.ts — and each panel binds only the switches it renders. Two copies of that list would be two copies of the storage key, and the first divergence would silently drop a reader's preference.
