命名空间
namespace	eve
	Build metadata (engine git commit, build time, third-party version).

namespace	eve::graphics
	卡牌游戏 UI 工具模块：工厂 + 脚本绑定入口。功能参考 ycarowr/UiCard：扇形手牌布局、抽牌/洗牌、悬浮放大、拖拽到落牌区、敌方手牌（背面/偷看）、费用不足置灰，以及可实时调节的布局参数。数据模型与渲染/交互逻辑见 CardTypes.h。

namespace	eve::graphics::hair
	Procedural hair/fur card meshes + material/LOD helpers (no strand simulation).

函数
Result< StrandsDatas >	eve::graphics::hair::filterStrandsByCurves (const StrandsDatas &src, const std::vector< uint32_t > &curveIndices)
	Copy a subset of curves into a new `StrandsDatas` (preserves point order).
