Amber Lump

An amber lump with an insect inside: a rounded drip-formed lump of fossil resin 0.35 m across on a flat-cut base at y=0, footprint 0.5 x 0.5 m.

风格：low-poly, flat-shaded vertex colors, no textures, 3 materials: the shared opaque one plus a distinct surface (glass, water or chrome), which stays its own mesh through mergeAssets rather than merging into the rest; shares palette and scale with its kit
