- Skybox now uses DBC sky colors (skyTop/skyMiddle/skyBand1/skyBand2) instead of hardcoded C++ color curves, with 3-band gradient and Rayleigh/Mie scattering - Clouds receive sun direction for lit edges, self-shadowing, and silver lining - Fixed sun quad box artifact with proper edge fade in celestial shader - Lens flare attenuated by fog, cloud density, and weather intensity - Replaced garish green/purple lens flare ghosts with warm natural palette - Added zone-based weather system for single-player mode with per-zone rain/snow configuration, probability-based activation, and smooth intensity transitions - Server SMSG_WEATHER remains authoritative when connected to a server
