Reactor Block

Outpost power reactor building, footprint exactly 8x8m, 2 floors at exactly 3m each with the roof line at 6m, chunky off-white hull mass on a gunmetal understructure with an astro orange hazard band at the base and a small cyan status strip.

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
