  "description": "公共施設の休憩所、玄関や歩道シーンに配置する汎用四輪ロレータ。後方が開いた歩行フレーム、前方キャスターと後輪、左右の握りと開口した手ブレーキ、ケーブル、休憩用座面、湾曲した前方背当てと座面下バッグを造形しています。車椅子や買い物カートではありません。人、荷物や追加の移動補助具は含みません。静的な外観用モデルで、移動支援・支持・ブレーキ・着座の実機能、医療用途、荷重定格や安全認証はなく、製品設計や操作指示ではありません。 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）0.617 × 0.926 × 0.725 m、11,240三角形。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 generic four-wheel rollator for public rest areas, entrances and sidewalk scenes. Its rear-open walking frame has front casters, rear wheels, paired grips with open handbrake levers and cables, rest seat, curved forward backrest and under-seat storage bag. This is not a wheelchair or shopping trolley. No person, load or additional mobility aid is included. Static appearance geometry provides no mobility-assistance, support, braking or seating function, clinical suitability, load rating or safety certification, and is not a product design or operating guidance. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.617 × 0.926 × 0.725 m; 11,240 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.",
