  "description": "ホテル玄関やロビーで使う荷物運搬カート。四つの旋回キャスター、縁付きのカーペット台、真鍮色の連続アーチ、押し手と上部ハンガーバーを備えます。荷物、ハンガー、走行・旋回・荷重や転倒安全の検証は含みません。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）0.760 × 1.996 × 1.169 m、12,116三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A bellhop cart for hotel entrances and lobbies, with four swivel-caster assemblies, an edged carpet platform, continuous brass-colored arches, push grips and overhead hanging rail. No luggage or hangers, rolling/swiveling behavior, load testing or tip-over safety validation is included. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.760 × 1.996 × 1.169 m; 12,116 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
