Curved Panel

Curved panel, a thin frosted glass sheet 0.005 m thick bent smoothly on a 0.8 m radius, 0.4 m tall (height 0.3-0.8 m), wrap 30-150 deg (default 60), 0.03 m corners, thin bright rim, face one decal slot; concave side toward +z, arc middle's back on z = 0.

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
