  "description": "店先の歩道に置く折りたたみ式のA型スタンド看板です。オーク調の木枠、両面の黒板パネル、上部の蝶番、開き止めのチェーン、ゴム足を造形しています。黒板は無地で、文字・メニュー・ロゴは含みません。開閉動作は付属しません。 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）0.605 × 0.958 × 0.350 m、1,784三角形。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 folding A-frame sidewalk sign for shopfronts. It models an oak-toned frame, chalkboard panels on both faces, top hinges, spreader chains and rubber feet. Both boards are blank, without lettering, menus or logos; the folding motion is not rigged. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.605 × 0.958 × 0.350 m; 1,784 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or mounting 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.",
