mow_sky

Summer-afternoon skydome for the freshcut lawn part. Renders on the inside of a large sphere: blue zenith → milky mid band → warm pale horizon, a hot sun disc with layered glow aligned to sun_dir, cumulus banks projected onto an overhead plane (perspective recession, no azimuth seam), a distant flat cloud deck near the horizon, and a faint cirrus veil. drift_t scrolls the clouds; cloud_cover sets how busy the sky is; grain dither keeps the gradients band-free.
