  "description": "旅客施設や公共建築の入口で検査導線を示す通過型ゲート。二枚の全高側面パネルと上部橋、足元の取付台、左右各12個の無発光表示窓、無表示の上部操作面、裏点検面・接続口を造形。独立した小売店用盗難防止ペデスタルとは異なる一体型アーチです。人物・床・隣接柵は含まず、検出・警報・認証や安全機能はありません。 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）1.284 × 2.348 × 0.581 m、7,032三角形。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 walk-through gate marking a screening route at passenger facilities or public-building entrances. It includes two full-height side panels with overhead bridge, wide mounting feet, twelve unlit indicator windows per side, blank header control face and rear access/connection details. This continuous arch differs from separate retail antitheft pedestals. People, floor and adjacent barriers are absent; no detection, alarms, authentication or safety functions are supplied. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 1.284 × 2.348 × 0.581 m; 7,032 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.",
