    #mizchi/kagura_core

    ホストや描画から独立した計算・データの層です。入力スナップショット、固定 timestep、 階層、地形・メッシュ生成を持ちます。値・状態・seed を受け取り、結果を返すか 呼び出し元の状態を更新します。GPU リソースやブラウザ／OS FFI は持ちません。

    geom、mesh3d、anim3d（骨格・IK）、pathfind は独立 module です。 physics2d、physics3d、collision3d、terrain3d、procedural3d はこの module の package です。 packing2d は矩形配置、particle3d は粒子の生成・運動・寿命、statistics は数値集計を担当します。 再生時間の Timeline は独立 module 内の anim3d/playback にあり、2D・3D・Web ビューアで共有します。

    描画 callback と実行オプションは mizchi/kagura_engine/application を使用します。 共通入力型は mizchi/kagura_core、押下差分と押下時間は core/inputstate。 WASD の移動・決定などの割り当てと InputHelper は game/inpututil が所有します。
