wck_sky

The worldClockKit sky: a sky-domain shader that draws every look the kit ships from one set of properties the director pushes each frame: a three-stop gradient (zenith, horizon, ground), a sun disc and glow, an optional second sun, a moon with its phase, a twinkling star field, a procedural cloud deck that thickens and darkens with the weather, haze toward the fog colour, posterised bands, a pixel-art mode (blocky rays, ordered dither, square sun), toon hard edges and a lightning flash. The sun and moon directions are properties rather than the scene light's direction, because at night the kit points the scene light at the moon.
