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< RibbonMesh >	eve::graphics::hair::buildRibbons (const StrandsDatas &strands, const RibbonParams &params={})
	Expand validated strands into stable (non-view-facing) ribbons.

void	eve::graphics::hair::appendRibbonMesh (RibbonMesh &dst, const RibbonMesh &src)
	Append `src` into `dst`, rebasing triangle indices by `dst` vertex count. @ownership Both meshes remain caller-owned; `src` is copied into `dst`.
