 本项目支持三套编译目标，分别对应开发流程的不同阶段：
 
-| 目标平台              | 显示后端            | 验证目的                            |
-|-------------------|-----------------|---------------------------------|
-| Windows (x86/x64) | SDL2 窗口         | 验证渲染逻辑、算法正确性、快速迭代调试             |
-| Linux x86_64      | SDL2 窗口         | 验证 Linux 兼容性、CMake 构建、SDL2 系统依赖 |
-| ARM Linux (交叉编译)  | SDL2 或 `/dev/fb0` | 最终在 IMX6U 开发板上运行的版本；优先目标以后续实际部署后端为准             |
