Observation Tower

Outpost observation tower, footprint exactly 4x4m, floors at exactly 3m pitch with an off-white hull shaft on a gunmetal lattice base and a wide cyan glazed cupola band at the top, a standard airlock collar.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
