Storage Depot

Pressurized storage depot building, footprint exactly 12x8m, 2 floors at exactly 3m each with the roof line at 6m, long off-white hull with gunmetal frame lines and an astro orange stripe under the eaves, 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
