+              <p><strong>改动：</strong><code>KeyFrame</code> 新增 <code>scene_assets</code> 和 <code>quality_report</code>；<code>KeyElement</code> 新增 <code>subject_kind</code> 与 <code>subject_assets</code>。后端新增 <code>generateSceneAsset</code> 和 <code>generateSubjectAssets</code>，主体资产支持白/黑背景、原尺寸/固定尺寸、物体视角、人物/生物动作与喜怒哀乐等表情；当已选关键帧共同指向一个主体时，前端会把这些帧作为 <code>source_frame_indices</code> 传入，后端拼接参考板。</p>
