Replace the sci-fi-colony dressing with two cosmetic classic-URP biomes in Game.unity: a lush Meadow_Forest base sanctuary (origin) and a hostile Arid_Desert survey expedition (+1000) - ~380 collider-stripped instances, warpgate/outpost landmarks, cyan/orange Aether accent lights. Warm daylight sun + Trilight ambient + a procedural daytime skybox + a cloned daylight post-FX grade (ACES kept). New client-only WorldAtmosphereSystem(+Config) cross-fades per-region fog/ambient by camera X>500 (mirrors HudSystem). Cosmetic-only - colliders stripped, never the subscene - so zero sim/netcode/PhysicsWorld impact (adversarially verified). Shadow-casting disabled on small foliage. EditMode 214/214. See DR-025.
