moor_sky

# moor_sky The sky over the moor in the hour before first light: a vertical gradient with a starfield, a few long stratus bars low over the horizon, a glow and a warm band around the sun, and the sun's own disc. Everything warm in it is aimed at `sun_direction`, which a sky-domain shader takes from the scene's directional light — so pointing the sun over the summit puts the whole dawn over the summit. That is the reason this exists rather than the engine's `ProceduralSky`, which derives the sun's azimuth from `timeOfDay` alone and puts sunrise at world +X with no field to turn it. The disc is drawn with no horizon test, because the hill is opaque geometry in front of the sky: the sun is hidden until it clears the summit, and then it IS the crest. `game.world.Dawn` drives every property from `game.vendor.dawn`.
